Description
Reserved
This bit is always read as 0. The write value should
always be 0.
Select the SCIF clock source and enable or disable
clock output from the SCK pin. Depending on CKE[1:0],
the SCK pin can be used for serial clock output or serial
clock input. If serial clock output is set in clocked
synchronous mode, set the C/A bit in SCSMR to 1, and
then set CKE[1:0].
