Note:
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 synchronous mode, and in the case of
external clock operation (CKE1 = 1). The setting of bits CKE1 and CKE0 must be carried out
before the SCI’s operating mode is determined using SMR.
For details of clock source selection, see table 15.9 in section 15.3, Operation.
