__HAL_RESET_HANDLE_STATE

#define __HAL_RESET_HANDLE_STATE

(

__HANDLE__

)

((__HANDLE__)->State = 0U)

Reset the Handle's State field.

Parameters

<strong>HANDLE</strong>

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.

Return values

None
