Choice of internal or external clock as the clock source
When internal clock is selected: SCI3 operates on the baud rate generator clock, and a clock
with the same frequency as the bit rate can be output.
When external clock is selected: A clock with a frequency 16 times the bit rate must be input.
(The on-chip baud rate generator is not used.)
Data transfer format: Fixed 8-bit data length
Overrun error (OER) detection during reception
Choice of internal or external clock as the clock source
When internal clock is selected: SCI3 operates on the baud rate generator clock, and a serial
clock is output.
When external clock is selected: The on-chip baud rate generator is not used, and SCI3
operates on the input serial clock.
