HAL_FACC_DeInit()

HAL_StatusTypeDef HAL_FACC_DeInit

(

FACC_HandleTypeDef *

facc

)

DeInit FACC Accelerator.

Return values

status,HAL_OK

if successful, otherwise failed

HAL_FACC_Init()

HAL_StatusTypeDef HAL_FACC_Init

(

FACC_HandleTypeDef *

facc

)

(

FACC_HandleTypeDef *

facc

)

Reset FACC Accelerator.

Parameters

facc	FACC handle

Return values

status,HAL_OK
