Section 13 Serial Communication Interface (SCI)
Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0): These bits are used to select the SCI clock
source and enable or disable clock output from the SCK pin. The combination of the CKE1 and
CKE0 bits determines whether the SCK pin functions as an I/O port, the serial clock output pin, or
the serial clock input pin.
The setting of the CKE0 bit, however, is only valid for internal clock operation (CKE1 = 0) in
asynchronous mode. The CKE0 bit setting is invalid in clocked synchronous mode, and in the case
of external clock operation (CKE1 = 1). Note that the SCI’s operating mode must be decided using
SMR before setting the CKE1 and CKE0 bits.
For details of clock source selection, see table 13.9.
