Section 17 Serial Communication Interface (SCI)
Bits 1 and 0—Clock Enable 1 and 0 (CKE1 and CKE0): These bits select the SCI clock source
and enable or disable clock output from the SCK0 pin. Depending on the combination of CKE1
and CKE0, the SCK0 pin can be used for serial clock output or serial clock input.
The CKE0 setting is valid only when the asynchronous mode and the internal clock are selected
(CKE1 = 0). The CKE0 setting is ignored in the clock synchronous mode, or when an external
clock source is selected (CKE1 = 1). Before selecting the SCI operating mode in the serial mode
register (SCSMR), set CKE1 and CKE0. For further details on selection of the SCI clock source,
see table 17.10 in section 17.3, Operation.
