89 * @param __HANDLE__: specifies the Peripheral Handle.
90 * @note This macro can be used for the following purpose:
91 * - When the Handle is declared as local variable; before passing it as parameter
92 * to HAL_PPP_Init() for the first time, it is mandatory to use this macro
93 * to set to 0 the Handle's "State" field.
94 * Otherwise, "State" field may have any random value and the first time the function
95 * HAL_PPP_Init() is called, the low level hardware initialization will be missed
96 * (i.e. HAL_PPP_MspInit() will not be executed).
97 * - When there is a need to reconfigure the low level hardware: instead of calling
98 * HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
99 * In this later function, when the Handle's "State" field is set to 0, it will execute the function
100 * HAL_PPP_MspInit() which will reconfigure the low level hardware.

163 RAM functions are defined using the toolchain options.
164 Functions that are executed in RAM should reside in a separate source module.
165 Using the 'Options for File' dialog you can simply change the 'Code / Const'
166 area of a module to a memory space in physical RAM.
167 Available memory areas are declared in the 'Target' tab of the 'Options for Target'
170 #define __RAM_FUNC HAL_StatusTypeDef
172 #elif defined ( __ICCARM__ )
175 RAM functions are defined using a specific toolchain keyword "__ramfunc".
177 #define __RAM_FUNC __ramfunc HAL_StatusTypeDef
179 #elif defined ( __GNUC__ )
182 RAM functions are defined using a specific toolchain attribute
183 "__attribute__((section(".RamFunc")))".
