  208. * Enter/Exit critical sections by ...
  209. *
  210. * CPU_CRITICAL_METHOD_INT_DIS_EN Disable/Enable interrupts
  211. * CPU_CRITICAL_METHOD_STATUS_STK Push/Pop interrupt status onto stack
  212. * CPU_CRITICAL_METHOD_STATUS_LOCAL Save/Restore interrupt status to local variable
  213. *
  214. * (a) CPU_CRITICAL_METHOD_INT_DIS_EN is NOT a preferred method since it does NOT support
  215. * multiple levels of interrupts. However, with some CPUs/compilers, this is the only
  216. * available method.
  217. *
  218. * (b) CPU_CRITICAL_METHOD_STATUS_STK is one preferred method since it supports multiple
  219. * levels of interrupts. However, this method assumes that the compiler provides C-level
  220. * &/or assembly-level functionality for the following :
  221. *
  222. * ENTER CRITICAL SECTION :
  223. * (1) Push/save interrupt status onto a local stack
  224. * (2) Disable interrupts
  225. *
  226. * EXIT CRITICAL SECTION :
  227. * (3) Pop/restore interrupt status from a local stack
  228. *
  229. * (c) CPU_CRITICAL_METHOD_STATUS_LOCAL is one preferred method since it supports multiple
  230. * levels of interrupts. However, this method assumes that the compiler provides C-level
  231. * &/or assembly-level functionality for the following :
  232. *
  233. * ENTER CRITICAL SECTION :
  234. * (1) Save interrupt status into a local variable
  235. * (2) Disable interrupts
  236. *
  237. * EXIT CRITICAL SECTION :
  238. * (3) Restore interrupt status from a local variable
  239. *
  240. * (2) Critical section macro's most likely require inline assembly. If the compiler does NOT
  241. * allow inline assembly in C source files, critical section macro's MUST call an assembly
  242. * subroutine defined in a 'cpu_a.asm' file located in the following software directory :
  243. *
  244. * \<CPU-Compiler Directory>\<cpu>\<compiler>\
  245. *
  246. * where
  247. * <CPU-Compiler Directory> directory path for common CPU-compiler software
  248. * <cpu> directory name for specific CPU
  249. * <compiler> directory name for specific compiler
  250. *
  251. * (3) (a) To save/restore interrupt status, a local variable 'cpu_sr' of type 'CPU_SR' MAY need
  252. * to be declared (e.g. if 'CPU_CRITICAL_METHOD_STATUS_LOCAL' method is configured).
  253. *
  254. * (1) 'cpu_sr' local variable SHOULD be declared via the CPU_SR_ALLOC() macro which, if
  255. * used, MUST be declared following ALL other local variables.
  256. *
  257. * Example :
  258. *
  259. * void Fnct (void)
  260. * {
  261. * CPU_INT08U val_08;
  262. * CPU_INT16U val_16;
  263. * CPU_INT32U val_32;
  264. * CPU_SR_ALLOC(); MUST be declared after ALL other local variables
  265. * :
  266. * :
  267. * }
  268. *
  269. * (b) Configure 'CPU_SR' data type with the appropriate-sized CPU data type large enough to
  270. * completely store the CPU's/compiler's status word.
