96 * HAL_PPP_Init() is called, the low level hardware initialization will be missed
|
|
|
97 * (i.e. HAL_PPP_MspInit() will not be executed).
|
|
|
98 * - When there is a need to reconfigure the low level hardware: instead of calling
|
|
|
99 * HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init().
|
|
|
100 * In this later function, when the Handle's "State" field is set to 0, it will execute the function
|
|
|
101 * HAL_PPP_MspInit() which will reconfigure the low level hardware.
