/** @brief Reset the Handle's State field.

  * @param __HANDLE__: specifies the Peripheral Handle.

  * @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
