For serial communication interface (SMIF bit in SCMR cleared to 0)
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 12.9
in section 12.3, Operation.
For smart card interface (SMIF bit in SCMR set to 1)
These bits, together with the GM bit in SMR, determine whether the SCK pin is used for
generic input/output or as the serial clock output pin.
2. The output clock frequency is the same as the bit rate.
3. The input clock frequency is 16 times the bit rate.
