Sampling at the falling edge of sampling clock*
*1 : Provide switch function whether sampling of reception data is performed at rising edge or falling edge of the
*2 : Serial clock delay function is used to delay half clock for the output signal of serial clock.
*3 : Refer to “ (2) Source Clock/Machine Clock” for t
(ESCR register : SCES bit = 1, ECCR register : SCDE bit = 1)
