Description
Clock Enable 1 and 0
These bits select the SCI clock source and enable or
disable clock output from the SCK pin. Depending on
the combination of CKE1 and CKE0, the SCK pin can
be used for serial clock output or serial clock input.
The CKE0 setting is valid only in the asynchronous
mode, and only when the SCI is internally clock (CKE1
synchronous mode, or when an external clock source is
selected (CKE1

set CKE1 and CKE0. For further details on selection of
the SCI clock source, see table 14.9.
