5.40 _9114_AD_FFHF_INT_Restart
@ Description
After calling _9114_AD_FFHF_INT_Start(), the AD conversion and transfer
won’t stop until the N blocks of the AD data is acquired, calling this function
can restart the FIFO half full interrupt transfer without re-initial all the relative
registers. However, if the interrupt operation was stopped by calling
_9114_AD_FFHF_INT_Stop(), the program should use
_9114_AD_FFHF_INT_Start() to restart the interrupt transfer function.
