/****************** USB OTG HS PHY CONFIGURATION *******************************
*  The USB OTG HS Core supports two PHY interfaces:
*   (i)  An ULPI interface for the external High Speed PHY: the USB HS Core will 
*        operate in High speed mode
*   (ii) An on-chip Full Speed PHY: the USB HS Core will operate in Full speed mode
*
*  You can select the PHY to be used using one of these two defines:
*   (i)  USE_ULPI_PHY: if the USB OTG HS Core is to be used in High speed mode 
*   (ii) USE_EMBEDDED_PHY: if the USB OTG HS Core is to be used in Full speed mode
*
*  Notes: 
*   - The USE_ULPI_PHY symbol is defined in the project compiler preprocessor as 
*     default PHY when HS core is used.
*   - On STM322xG-EVAL and STM324xG-EVAL boards, only configuration(i) is available.
*     Configuration (ii) need a different hardware, for more details refer to your
*     STM32 device datasheet.

*                      FIFO Size Configuration in Device mode
*  
*  (i) Receive data FIFO size = RAM for setup packets + 
*                   OUT endpoint control information +
*                   data OUT packets + miscellaneous
*      Space = ONE 32-bits words
*     --> RAM for setup packets = 10 spaces
*        (n is the nbr of CTRL EPs the device core supports) 
*     --> OUT EP CTRL info      = 1 space
*        (one space for status information written to the FIFO along with each 
*        received packet)
*     --> data OUT packets      = (Largest Packet Size / 4) + 1 spaces 
*        (MINIMUM to receive packets)
*     --> OR data OUT packets  = at least 2*(Largest Packet Size / 4) + 1 spaces 
*        (if high-bandwidth EP is enabled or multiple isochronous EPs)
*     --> miscellaneous = 1 space per OUT EP
*        (one space for transfer complete status information also pushed to the 
*        FIFO with each endpoint's last packet)
*
*  (ii)MINIMUM RAM space required for each IN EP Tx FIFO = MAX packet size for 
*       that particular IN EP. More space allocated in the IN EP Tx FIFO results
*       in a better performance on the USB and can hide latencies on the AHB.
*
*  (iii) TXn min size = 16 words. (n  : Transmit FIFO index)
*   (iv) When a TxFIFO is not used, the Configuration should be as follows: 
*       case 1 :  n > m    and Txn is not used    (n,m  : Transmit FIFO indexes)
*       --> Txm can use the space allocated for Txn.
*       case2  :  n < m    and Txn is not used    (n,m  : Transmit FIFO indexes)
*       --> Txn should be configured with the minimum space of 16 words
*  (v) The FIFO is used optimally when used TxFIFOs are allocated in the top 
*       of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones.

/*******************************************************************************
*                     FIFO Size Configuration in Host mode
*  
*  (i) Receive data FIFO size = (Largest Packet Size / 4) + 1 or 
*                             2x (Largest Packet Size / 4) + 1,  If a 
*                             high-bandwidth channel or multiple isochronous 
*                             channels are enabled
*
*  (ii) For the host nonperiodic Transmit FIFO is the largest maximum packet size 
*      for all supported nonperiodic OUT channels. Typically, a space 
*      corresponding to two Largest Packet Size is recommended.
*
*  (iii) The minimum amount of RAM required for Host periodic Transmit FIFO is 
*        the largest maximum packet size for all supported periodic OUT channels.
*        If there is at least one High Bandwidth Isochronous OUT endpoint, 
*        then the space must be at least two times the maximum packet size for 
*        that channel.
