12.6.2.2 Clock Selection Circuit

A clock can be selected by setting the modes and the register.

Modes can be specified by setting the SCxMOD0<SM[1:0]>

The clock in I/O interface mode is selected by setting SCxCR<IOC><SCLKS>.

The clock in UART mode is selected by setting SCxMOD0<SC[1:0]>.

SCLKx pin input

To use SCLKx input, the following conditions must be satisfied.

・

If double buffer is used

- SCLK cycle > 6/fsys

・

If double buffer is not used

- SCLK cycle > 8/fsys
