REJ09B0146-0500
On-chip baud rate generator with selectable bit rates
Internal or external transmit/receive clock source
From either baud rate generator (internal) or SCK0 pin (external)
Four types of interrupts
Transmit-data-empty, transmit-end, receive-data-full, and receive-error interrupts are requested
independently.
Saving power
When the SCI is not in use, it can be stopped by halting the clock supply for the saving power.
