Four interrupt sources
There are four interrupt sources—transmit-FIFO-data-empty, break, receive-FIFO-data-full,
and receive-error—that can issue requests independently.
The DMA controller (DMAC) can be activated to execute a data transfer by issuing a DMA
transfer request in the event of a transmit-FIFO-data-empty or receive-FIFO-data-full interrupt.
When not in use, the SCIF can be stopped by halting its clock supply to reduce power
consumption.
Modem control functions (
The amount of data in the transmit/receive FIFO registers, and the number of receive errors in
the receive data in the receive FIFO register, can be ascertained.
A timeout error (DR) can be detected during reception.
