Clock
Either an internal clock generated by the on-chip baud rate generator or an external clock input at
the SCK2 pin can be selected as the SCIF’s serial clock, according to the setting of the CKE1 bit
in SCSCR2. For details of SCIF clock source selection, see table 16.4.
When an external clock is input at the SCK2 pin, the clock frequency should be 16 times the bit
rate used.
When operating using the internal clock, the clock can be output via the SCK2 pin. The frequency
of this clock is 16 times the bit rate.
