- * @version V1.5.0
- * @date    06-March-2015
- * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
- *          This file contains the system clock configuration for STM32F4xx devices.
- *
- * 1.  This file provides two functions and one global variable to be called from
- *     user application:
- *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
- *                      and Divider factors, AHB/APBx prescalers and Flash settings),
- *                      depending on the configuration made in the clock xls tool.
- *                      This function is called at startup just after reset and
- *                      before branch to main program. This call is made inside
- *                      the "startup_stm32f4xx.s" file.
- *
- *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
- *                                  by the user application to setup the SysTick
- *                                  timer or configure other parameters.
- *
- *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
- *                                 be called whenever the core clock is changed
- *                                 during program execution.
- *
- * 2. After each device reset the HSI (16 MHz) is used as system clock source.
- *    Then SystemInit() function is called, in "startup_stm32f4xx.s" file, to
- *    configure the system clock before to branch to main program.
- *
- * 3. If the system clock source selected by user fails to startup, the SystemInit()
- *    function will do nothing and HSI still used as system clock source. User can
- *    add some code to deal with this issue inside the SetSysClock() function.
- *
- * 4. The default value of HSE crystal is set to 25MHz, refer to "HSE_VALUE" define
- *    in "stm32f4xx.h" file. When HSE is used as system clock source, directly or
- *    through PLL, and you are using different crystal you have to adapt the HSE
- *    value to your own configuration.
- *
- * 5. This file configures the system clock as follows:

- *         be used by the user application to setup the SysTick timer or configure
- *         other parameters.
- *
- * @note   Each time the core clock (HCLK) changes, this function must be called
- *         to update SystemCoreClock variable value. Otherwise, any configuration
- *         based on this variable will be incorrect.
- *
- * @note   - The system frequency computed by this function is not the real
- *           frequency in the chip. It is calculated based on the predefined
- *           constant and the selected clock source:
- *
- *           - If SYSCLK source is HSI, SystemCoreClock will contain the HSI_VALUE(*)
- *
- *           - If SYSCLK source is HSE, SystemCoreClock will contain the HSE_VALUE(**)
- *
- *           - If SYSCLK source is PLL, SystemCoreClock will contain the HSE_VALUE(**)
- *             or HSI_VALUE(*) multiplied/divided by the PLL factors.
- *
- *         (*) HSI_VALUE is a constant defined in stm32f4xx.h file (default value
- *             16 MHz) but the real value may vary depending on the variations
- *             in voltage and temperature.
- *
- *         (**) HSE_VALUE is a constant defined in stm32f4xx.h file (default value
- *              25 MHz), user has to ensure that HSE_VALUE is same as the real
- *              frequency of the crystal used. Otherwise, this function may
- *              have wrong result.
- *
- *         - The result of this function could be not correct when using fractional

+ * @author  MCD Application Team
+ * @version V1.5.0
+ * @date    06-March-2015
+ * @brief   CMSIS Cortex-M4 Device Peripheral Access Layer System Source File.
+ *          This file contains the system clock configuration for STM32F4xx devices.
+ *
+ * 1.  This file provides two functions and one global variable to be called from
+ *     user application:
+ *      - SystemInit(): Setups the system clock (System clock source, PLL Multiplier
+ *                      and Divider factors, AHB/APBx prescalers and Flash settings),
+ *                      depending on the configuration made in the clock xls tool.
+ *                      This function is called at startup just after reset and
+ *                      before branch to main program. This call is made inside
+ *                      the "startup_stm32f4xx.s" file.
+ *
+ *      - SystemCoreClock variable: Contains the core clock (HCLK), it can be used
+ *                                  by the user application to setup the SysTick
+ *                                  timer or configure other parameters.
+ *
+ *      - SystemCoreClockUpdate(): Updates the variable SystemCoreClock and must
+ *                                 be called whenever the core clock is changed
+ *                                 during program execution.
+ *
+ * 2. After each device reset the HSI (16 MHz) is used as system clock source.
+ *    Then SystemInit() function is called, in "startup_stm32f4xx.s" file, to
+ *    configure the system clock before to branch to main program.
+ *
+ * 3. If the system clock source selected by user fails to startup, the SystemInit()
+ *    function will do nothing and HSI still used as system clock source. User can
+ *    add some code to deal with this issue inside the SetSysClock() function.
+ *
+ * 4. The default value of HSE crystal is set to 25MHz, refer to "HSE_VALUE" define
+ *    in "stm32f4xx.h" file. When HSE is used as system clock source, directly or
+ *    through PLL, and you are using different crystal you have to adapt the HSE
+ *    value to your own configuration.
+ *
+ * 5. This file configures the system clock as follows:

-<h3>How to Port</h3>
-
-<h4>Basic considerations</h4>
-<p>The FatFs module is assuming following conditions on portability.</p>
-<ul>
-<li>ANSI C<br>
-The FatFs module is a middleware written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
-<li>Size of integer types<br>
-The FatFs module assumes that size of char/short/long are 8/16/32 bit and int is 16 or 32 bit. These correspondence are defined in <tt>integer.h</tt>. This will not be a problem on most compilers. When any conflict with existing definitions is occured, you must resolve it with care.</li>
-</ul>
-
-<h4>System organizations</h4>
-<p>The dependency diagram shown below is a typical configuration of the embedded system with FatFs module.</p>
-<p><img src="../img/modules.png" width="580" height="280" alt="dependency diagram"></p>
-<p>(a) If a working disk module with FatFs API is provided, no additional function is needed. (b) To attach existing disk drivers with different API, glue functions are needed to translate the APIs between FatFs and the drivers.</p>
-<p><img src="../img/funcs.png" width="680" height="430" alt="functional diagram"></p>
-
-<h4>Which function is required?</h4>
-<p>You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. Most of defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.</p>
-<table class="lst2">
-<tr><th>Function</th><th>Required when:</th><th>Note</th></tr>

-<h3>Long File Name</h3>
-<p>FatFs module supports LFN (long file name). The two different file names, SFN (short file name) and LFN, of a file is transparent on the API except for <tt>f_readdir()</tt> function. The LFN feature is disabled by default. To enable it, set <tt>_USE_LFN</tt> to 1, 2 or 3, and add <tt>option/unicode.c</tt> to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by <tt>_MAX_LFN</tt> according to the available memory. The length of an LFN will reach up to 255 characters, so that the <tt>_MAX_LFN</tt> should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the input file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When enable the LFN feature with re-entrant configuration, <tt>_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(_MAX_LFN + 1) * 2</tt> bytes.</p>
-<table class="lst2 rset">

-<p>When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with those code pages will not able to be implemented to most 8-bit microcontrollers.</p>
-<p>Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the LFN feature. FatFs can swich the LFN feature off by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.</p>
-</div>
-
-<div class="para" id="unicode">
-<h3>Unicode API</h3>
-<p>By default, FatFs uses ANSI/OEM code set on the API under LFN configuration. FatFs can also switch the character encoding to Unicode on the API by <tt>_LFN_UNICODE</tt> option. This means that the FatFs supports the True-LFN feature. For more information, refer to the description in the <a href="filename.html">file name</a>.</p>
-</div>
-
-<div class="para" id="reentrant">
-<h3>Re-entrancy</h3>
-<p>The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe by <tt>_FS_REENTRANT</tt> option. In this case, also the OS dependent synchronization object control functions, <tt>ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant() and ff_rel_grant()</tt> must be added to the project. There are some examples in the <tt>option/syscall.c</tt>.</p>
-<p>When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves the file function. If wait time exceeded a period defined by <tt>_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout feature might not be supported by some RTOS.</p>
-<p>There is an exception for <tt>f_mount(), f_mkfs(), f_fdisk()</tt> function. These functions are not re-entrant to the same volume or corresponding physical drive. When use these functions, all other tasks must unmount the volume and avoid to access the volume.</p>
-<p>Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer will need to be re-entrant.</p>

-<div class="para" id="dup">
-<h3>Duplicated File Access</h3>
-<p>FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed and deleted. A violation of these rules can cause data colluption.</p>
-<p>The file lock control can be enabled by <tt>_FS_LOCK</tt> option. The value of option defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with <tt>FR_LOCKED</tt>. If number of open objects, files and sub-directories, is equal to <tt>_FS_LOCK</tt>, an extra <tt>f_open(), f_optndir()</tt> function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>

-<div class="para" id="fs1">
-<h3>Performance Effective File Access</h3>
-<p>For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by <tt>f_read()</tt> function.</p>
-<p>Figure 1. Sector misaligned read (short)<br>
-<img src="../img/f1.png" width="490" height="110" alt="">
-</p>
-<p>Figure 2. Sector misaligned read (long)<br>
-<img src="../img/f2.png" width="490" height="140" alt="">
-</p>
-<p>Figure 3. Fully sector aligned read<br>
-<img src="../img/f3.png" width="490" height="119" alt="">
-</p>
-<p>The file I/O buffer is a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option <tt>_FS_TINY</tt> determins which sector buffer is used for the file data transfer. When tiny buffer configuration (1) is selected, data memory consumption is reduced <tt>_MAX_SS</tt> bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
-<p>Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with <tt>disk_read()</tt> function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.</p>
-<p>Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>

-<h3>Considerations on Flash Memory Media</h3>
-<p>To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.</p>
-<h4>Using Mutiple-Sector Write</h4>
-<div class="rset">
-Figure 6. Comparison between Multiple/Single Sector Write<br>
-<img src="../img/f6.png" width="630" height="148" alt="fig.6">
-</div>
-<p>The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. <a href="../img/rwtest2.png">This graph</a> is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. The number of write transactions also affects the life time of the flash memory media. Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write feature. </p>
-<h4>Forcing Memory Erase</h4>
-<p>When remove a file with <tt>f_remove()</tt> function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data is forced erased on removing the file, those data blocks will be turned in to the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this feature by setting <tt>_USE_ERASE</tt> to 1. Note that this is an expectation of internal process of the flash memory storage and not that always effective. Also <tt>f_remove()</tt> function will take a time when remove a large file. Most applications will not need this feature.</p>

-<div class="para" id="critical">
-<h3>Critical Section</h3>
-<p>If a write operation to the FAT volume is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.</p>

-<br class="clr">
-<p>An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.</p>
-<ul>
-<li>The file data being rewrited is collapsed.</li>
-<li>The file being appended returns initial state.</li>
-<li>The file created as new is gone.</li>
-<li>The file created as new or overwritten remains but no content.</li>
-<li>Efficiency of disk use gets worse due to lost clusters.</li>
-</ul>
-<p>Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using <tt>f_sync()</tt> function as shown in Figure 5.</p>

+<h3>How to Port</h3>
+
+<h4>Basic considerations</h4>
+<p>The FatFs module is assuming following conditions on portability.</p>
+<ul>
+<li>ANSI C<br>
+The FatFs module is a middleware written in ANSI C (C89). There is no platform dependence, so long as the compiler is in compliance with ANSI C.</li>
+<li>Size of integer types<br>
+The FatFs module assumes that size of char/short/long are 8/16/32 bit and int is 16 or 32 bit. These correspondence are defined in <tt>integer.h</tt>. This will not be a problem on most compilers. When any conflict with existing definitions is occured, you must resolve it with care.</li>
+</ul>
+
+<h4>System organizations</h4>
+<p>The dependency diagram shown below is a typical configuration of the embedded system with FatFs module.</p>
+<p><img src="../img/modules.png" width="580" height="280" alt="dependency diagram"></p>
+<p>(a) If a working disk module with FatFs API is provided, no additional function is needed. (b) To attach existing disk drivers with different API, glue functions are needed to translate the APIs between FatFs and the drivers.</p>
+<p><img src="../img/funcs.png" width="680" height="430" alt="functional diagram"></p>
+
+<h4>Which function is required?</h4>
+<p>You need to provide only low level disk I/O functions that required by FatFs module and nothing else. If a working disk module for the target is already existing, you need to write only glue functions to attach it to the FatFs module. If not, you need to port any other disk module or write it from scratch. Most of defined functions are not that always required. For example, disk write function is not required in read-only configuration. Following table shows which function is required depends on configuration options.</p>

+<h3>Long File Name</h3>
+<p>FatFs module supports LFN (long file name). The two different file names, SFN (short file name) and LFN, of a file is transparent on the API except for <tt>f_readdir()</tt> function. The LFN feature is disabled by default. To enable it, set <tt>_USE_LFN</tt> to 1, 2 or 3, and add <tt>option/unicode.c</tt> to the project. The LFN feature requiers a certain working buffer in addition. The buffer size can be configured by <tt>_MAX_LFN</tt> according to the available memory. The length of an LFN will reach up to 255 characters, so that the <tt>_MAX_LFN</tt> should be set to 255 for full featured LFN operation. If the size of working buffer is insufficient for the input file name, the file function fails with <tt>FR_INVALID_NAME</tt>. When enable the LFN feature with re-entrant configuration, <tt>_USE_LFN</tt> must be set to 2 or 3. In this case, the file function allocates the working buffer on the stack or heap. The working buffer occupies <tt>(_MAX_LFN + 1) * 2</tt> bytes.</p>
+<table class="lst2 rset">

+</table>
+<p>When the LFN feature is enabled, the module size will be increased depends on the selected code page. Right table shows how many bytes increased when LFN feature is enabled with some code pages. Especially, in the CJK region, tens of thousands of characters are being used. Unfortunately, it requires a huge OEM-Unicode bidirectional conversion table and the module size will be drastically increased that shown in the table. As the result, the FatFs with LFN feature with those code pages will not able to be implemented to most 8-bit microcontrollers.</p>
+<p>Note that the LFN feature on the FAT file system is a patent of Microsoft Corporation. This is not the case on FAT32 but most FAT32 drivers come with the LFN feature. FatFs can swich the LFN feature off by configuration option. When enable LFN feature on the commercial products, a license from Microsoft may be required depends on the final destination.</p>
+</div>
+
+<div class="para" id="unicode">
+<h3>Unicode API</h3>
+<p>By default, FatFs uses ANSI/OEM code set on the API under LFN configuration. FatFs can also switch the character encoding to Unicode on the API by <tt>_LFN_UNICODE</tt> option. This means that the FatFs supports the True-LFN feature. For more information, refer to the description in the <a href="filename.html">file name</a>.</p>
+</div>
+
+<div class="para" id="reentrant">
+<h3>Re-entrancy</h3>
+<p>The file operations to the different volume is always re-entrant and can work simultaneously. The file operations to the same volume is not re-entrant but it can also be configured to thread-safe by <tt>_FS_REENTRANT</tt> option. In this case, also the OS dependent synchronization object control functions, <tt>ff_cre_syncobj(), ff_del_syncobj(), ff_req_grant() and ff_rel_grant()</tt> must be added to the project. There are some examples in the <tt>option/syscall.c</tt>.</p>
+<p>When a file function is called while the volume is in use by any other task, the file function is suspended until that task leaves the file function. If wait time exceeded a period defined by <tt>_TIMEOUT</tt>, the file function will abort with <tt>FR_TIMEOUT</tt>. The timeout feature might not be supported by some RTOS.</p>
+<p>There is an exception for <tt>f_mount(), f_mkfs(), f_fdisk()</tt> function. These functions are not re-entrant to the same volume or corresponding physical drive. When use these functions, all other tasks must unmount the volume and avoid to access the volume.</p>
+<p>Note that this section describes on the re-entrancy of the FatFs module itself but also the low level disk I/O layer will need to be re-entrant.</p>
+</div>
+
+<div class="para" id="dup">
+<h3>Duplicated File Access</h3>
+<p>FatFs module does not support the read/write collision control of duplicated open to a file. The duplicated open is permitted only when each of open method to a file is read mode. The duplicated open with one or more write mode to a file is always prohibited, and also open file must not be renamed and deleted. A violation of these rules can cause data colluption.</p>
+<p>The file lock control can be enabled by <tt>_FS_LOCK</tt> option. The value of option defines the number of open objects to manage simultaneously. In this case, if any open, rename or remove that violating the file shareing rule that described above is attempted, the file function will fail with <tt>FR_LOCKED</tt>. If number of open objects, files and sub-directories, is equal to <tt>_FS_LOCK</tt>, an extra <tt>f_open(), f_optndir()</tt> function will fail with <tt>FR_TOO_MANY_OPEN_FILES</tt>.</p>
+</div>
+
+<div class="para" id="fs1">
+<h3>Performance Effective File Access</h3>
+<p>For good read/write throughput on the small embedded systems with limited size of memory, application programmer should consider what process is done in the FatFs module. The file data on the volume is transferred in following sequence by <tt>f_read()</tt> function.</p>
+<p>Figure 1. Sector misaligned read (short)<br>
+<img src="../img/f1.png" width="490" height="110" alt="">
+</p>
+<p>Figure 2. Sector misaligned read (long)<br>
+<img src="../img/f2.png" width="490" height="140" alt="">
+</p>
+<p>Figure 3. Fully sector aligned read<br>
+<img src="../img/f3.png" width="490" height="119" alt="">
+</p>
+<p>The file I/O buffer is a sector buffer to read/write a partial data on the sector. The sector buffer is either file private sector buffer on each file object or shared sector buffer in the file system object. The buffer configuration option <tt>_FS_TINY</tt> determins which sector buffer is used for the file data transfer. When tiny buffer configuration (1) is selected, data memory consumption is reduced <tt>_MAX_SS</tt> bytes each file object. In this case, FatFs module uses only a sector buffer in the file system object for file data transfer and FAT/directory access. The disadvantage of the tiny buffer configuration is: the FAT data cached in the sector buffer will be lost by file data transfer and it must be reloaded at every cluster boundary. However it will be suitable for most application from view point of the decent performance and low memory comsumption.</p>
+<p>Figure 1 shows that a partial sector, sector misaligned part of the file, is transferred via the file I/O buffer. At long data transfer shown in Figure 2, middle of transfer data that covers one or more sector is transferred to the application buffer directly. Figure 3 shows that the case of entier transfer data is aligned to the sector boundary. In this case, file I/O buffer is not used. On the direct transfer, the maximum extent of sectors are read with <tt>disk_read()</tt> function at a time but the multiple sector transfer is divided at cluster boundary even if it is contiguous.</p>
+<p>Therefore taking effort to sector aligned read/write accesss eliminates buffered data transfer and the read/write performance will be improved. Besides the effect, cached FAT data will not be flushed by file data transfer at the tiny configuration, so that it can achieve same performance as non-tiny configuration with small memory footprint.</p>
+</div>
+
+<div class="para" id="fs2">
+<h3>Considerations on Flash Memory Media</h3>
+<p>To maximize the write performance of flash memory media, such as SDC, CFC and U Disk, it must be controlled in consideration of its characteristitcs.</p>
+<h4>Using Mutiple-Sector Write</h4>
+<div class="rset">
+Figure 6. Comparison between Multiple/Single Sector Write<br>
+<img src="../img/f6.png" width="630" height="148" alt="fig.6">
+</div>
+<p>The write throughput of the flash memory media becomes the worst at single sector write transaction. The write throughput increases as the number of sectors per a write transaction. This effect more appers at faster interface speed and the performance ratio often becomes grater than ten. <a href="../img/rwtest2.png">This graph</a> is clearly explaining how fast is multiple block write (W:16K, 32 sectors) than single block write (W:100, 1 sector), and also larger card tends to be slow at single block write. The number of write transactions also affects the life time of the flash memory media. Therefore the application program should write the data in large block as possible. The ideal write chunk size and alighment is size of sector, and size of cluster is the best. Of course all layers between the application and the storage device must have consideration on multiple sector write, however most of open-source disk drivers lack it. Do not split a multiple sector write request into single sector write transactions or the write throughput gets poor. Note that FatFs module and its sample disk drivers supprt multiple sector read/write feature. </p>
+<h4>Forcing Memory Erase</h4>
+<p>When remove a file with <tt>f_remove()</tt> function, the data clusters occupied by the file are marked 'free' on the FAT. But the data sectors containing the file data are not that applied any process, so that the file data left occupies a part of the flash memory array as 'live block'. If the file data is forced erased on removing the file, those data blocks will be turned in to the free block pool. This may skip internal block erase operation to the data block on next write operation. As the result the write performance might be improved. FatFs can manage this feature by setting <tt>_USE_ERASE</tt> to 1. Note that this is an expectation of internal process of the flash memory storage and not that always effective. Also <tt>f_remove()</tt> function will take a time when remove a large file. Most applications will not need this feature.</p>

+
+<div class="para" id="critical">
+<h3>Critical Section</h3>
+<p>If a write operation to the FAT volume is interrupted due to any accidental failure, such as sudden blackout, incorrect disk removal and unrecoverable disk error, the FAT structure on the volume can be broken. Following images shows the critical section of the FatFs module.</p>
+<div class="lset">

+<br class="clr">
+<p>An interruption in the red section can cause a cross link; as a result, the object being changed can be lost. If an interruption in the yellow section is occured, there is one or more possibility listed below.</p>

+<li>The file being appended returns initial state.</li>
+<li>The file created as new is gone.</li>
+<li>The file created as new or overwritten remains but no content.</li>
+<li>Efficiency of disk use gets worse due to lost clusters.</li>

+<p>Each case does not affect the files that not opened in write mode. To minimize risk of data loss, the critical section can be minimized by minimizing the time that file is opened in write mode or using <tt>f_sync()</tt> function as shown in Figure 5.</p>

-<h4>Description</h4>
-<p>The memory address specified by <tt class="arg">buff</tt> is not that always aligned to word boundary because the type of argument is defined as <tt>BYTE*</tt>. The misaligned read/write request can occure at <a href="appnote.html#fs1">direct transfer</a>. If the bus architecture, especially DMA controller, does not allow misaligned memory access, it should be solved in this function. There are some workarounds described below to avoid this issue.</p>
-<ul>
-<li>Convert word transfer to byte transfer in this function. - Recommended.</li>
-<li>For <tt>f_read()</tt>, avoid long read request that includes a whole of sector. - Direct transfer will never occure.</li>
-<li>For <tt>f_read(fp, buff, btr, &amp;br)</tt>, make sure that <tt>(((UINT)buff &amp; 3) == (f_tell(fp) &amp; 3))</tt> is true. - Word aligned direct transfer is guaranteed.</li>
-</ul>
-<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will not get good read throughput.</p>

+<h4>Description</h4>
+<p>The memory address specified by <tt class="arg">buff</tt> is not that always aligned to word boundary because the type of argument is defined as <tt>BYTE*</tt>. The misaligned read/write request can occure at <a href="appnote.html#fs1">direct transfer</a>. If the bus architecture, especially DMA controller, does not allow misaligned memory access, it should be solved in this function. There are some workarounds described below to avoid this issue.</p>
+<ul>
+<li>Convert word transfer to byte transfer in this function. - Recommended.</li>
+<li>For <tt>f_read()</tt>, avoid long read request that includes a whole of sector. - Direct transfer will never occure.</li>
+<li>For <tt>f_read(fp, buff, btr, &amp;br)</tt>, make sure that <tt>(((UINT)buff &amp; 3) == (f_tell(fp) &amp; 3))</tt> is true. - Word aligned direct transfer is guaranteed.</li>
+</ul>
+<p>Generally, a multiple sector transfer request must not be split into single sector transactions to the storage device, or you will not get good read throughput.</p>
