## Detailed Description

exFlash control functions

     ===============================================================================

     ===============================================================================
        [..]
        This subsection provides a set of functions allowing to control the exFlash.
         (+) hal_exflash_get_state()API can be helpful to check in run-time the state of the exFlash peripheral.
         (+) hal_exflash_get_error() check in run-time Errors occurring during communication.
         (+) hal_exflash_set_timeout() set the timeout during internal process.
