Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Clock Enable
These bits select the SCIF clock source and enable or
disable clock output from the SCK2 pin. Depending on the
combination of CKE1 and CKE0, the SCK2 pin can be
used for serial clock output or serial clock input.
The CKE0 setting is valid only when the SCI is operating
with the internal clock (CKE1
ignored when an external clock source is selected (CKE1
1). Always select the SCIF operating mode in the
SCSMR2, before setting CKE1 and CKE0. For further
details on selection of the SCIF clock source, see table
16.7 in section 16.4, Operation.
