Description
Clock Enable 1 and 0
Select the SCIF clock source and enable or disable
clock output from the SCIFnCK pin. The combination
of the CKE1 bit and CKE0 bit determines whether the
SCIFnCK pin is set as a serial clock output pin or a
serial clock input pin. The setting of the CKE0 bit is
available in internal clock operation (CKE1 = 0). In the
case of external clock operation (CKE1 = 1), the
setting of the CKE0 bit is not available. The CKE1
and CKE0 bits must be set before the SCIF operating
mode is selected by SCSMR.
