Bits 1 and 0—Clock Enable 1 and 0 (CKE1, CKE0): These bits select the SCI clock source and
enable or disable clock output from the SCK pin. Depending on the settings of CKE1 and CKE0,
the SCK pin can be used for generic input/output, serial clock output, or serial clock input.
The CKE0 setting is valid only in asynchronous mode, and only when the SCI is internally
clocked (CKE1 = 0). The CKE0 setting is ignored in synchronous mode, or when an external
clock source is selected (CKE1 = 1). Select the SCI operating mode in SMR before setting the
CKE1 and CKE0 bits. For further details on selection of the SCI clock source, see table 13.9 in
section 13.3, Operation.
