• Four types of interrupts: Transmit-FIFO-data-empty, break, receive-FIFO-data-full, and
• When the SCIF is not in use, it can be stopped by halting the clock supplied to it, saving
• In asynchronous, on-chip modem control functions (RTS and CTS).

• A time-out error (DR) can be detected when receiving in asynchronous mode.
Figure 19.1 shows a block diagram of the SCIF for each channel.

errors of the receive data in the receive FIFO register can be ascertained.
