72/** @brief Reset the Handle's State field.
73 * @param __HANDLE__: specifies the Peripheral Handle.
74 * @note This macro can be used for the following purpose:
75 * - When the Handle is declared as local variable; before passing it as parameter
76 * to HAL_PPP_Init() for the first time, it is mandatory to use this macro
77 * to set to 0 the Handle's "State" field.
78 * Otherwise, "State" field may have any random value and the first time the function
79 * HAL_PPP_Init() is called, the low level hardware initialization will be missed
80 * (i.e. HAL_PPP_MspInit() will not be executed).
81 * - When there is a need to reconfigure the low level hardware: instead of calling
82 * HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
83 * In this later function, when the Handle's "State" field is set to 0, it will execute the function
84 * HAL_PPP_MspInit() which will reconfigure the low level hardware.
85 * @retval None

156 RAM functions are defined using the toolchain options.
157 Functions that are executed in RAM should reside in a separate source module.
158 Using the 'Options for File' dialog you can simply change the 'Code / Const'
159 area of a module to a memory space in physical RAM.
160 Available memory areas are declared in the 'Target' tab of the 'Options for Target'
161 dialog.
