||
| 81 | * (i.e. HAL_PPP_MspInit() will not be executed). |
||
| 82 | * - When there is a need to reconfigure the low level hardware: instead of calling |
||
| 83 | * HAL_PPP_DeInit() then HAL_PPP_Init(), user can make a call to this macro then HAL_PPP_Init(). |
||
| 84 | * In this later function, when the Handle's "State" field is set to 0, it will execute the function |
||
| 85 | * HAL_PPP_MspInit() which will reconfigure the low level hardware. |
