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