597  (++) Blocking mode: The communication is performed in polling mode.
598  The HAL status of all data processing is returned by the same function
599  after finishing transfer.
600  (++) No-Blocking mode: The communication is performed using Interrupts
601  , These APIs return the HAL status.
602  The end of the data processing will be indicated through the
603  dedicated PKC IRQ when using Interrupt mode.
604  The hal_pkc_done_callback() user callbacks will be executed respectively at the end of the calculate process
