Internal or external transmit/receive clock source: From either baud rate generator (internal) or
SCK pin (external)
Four types of interrupts: Transmit-data-empty, transmit-end, receive-data-full, and receive-
error interrupts are requested independently.
When the SCI is not in use, it can be stopped by halting the clock supplied to it, saving power.
