| * @note This macro can be used for the following purpose: |
| * - When the Handle is declared as local variable; before passing it as parameter |
| * to HAL_PPP_Init() for the first time, it is mandatory to use this macro |
| * to set to 0 the Handle's "State" field. |
| * Otherwise, "State" field may have any random value and the first time the function |
| * HAL_PPP_Init() is called, the low level hardware initialization will be missed |
| * (i.e. HAL_PPP_MspInit() will not be executed). |
| * - When there is a need to reconfigure the low level hardware: instead of calling |
| * HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init(). |
| * In this later function, when the Handle's "State" field is set to 0, it will execute the function |
| * HAL_PPP_MspInit() which will reconfigure the low level hardware. |
| * @retval None |
