|
|
* - 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.
