15. Serial Communication Interface (SCI)
• Full-duplex communication capability
• On-chip baud rate generator allows any bit rate to be selected.
• Choice of serial clock source: internal clock from baud rate generator or external clock from
• Four interrupt sources
• When not in use, the SCI can be stopped by halting its clock supply to reduce power

⎯ Synchronous mode
The transmitter and receiver are mutually independent, enabling transmission and reception to
be executed simultaneously. Double-buffering is used in both the transmitter and the receiver,
enabling continuous transmission and continuous reception of serial data.
SCK pin
There are four interrupt sources—transmit-data-empty, transmit-end, receive-data-full, and
receive-error—that can issue requests independently. The transmit-data-empty interrupt and
receive-data-full interrupt can activate the DMA controller (DMAC) to execute a data transfer.
consumption.
Serial data communication is synchronized with a clock. Serial data communication can be
carried out with other chips that have a synchronous communication function.
There is a single serial data transfer format.
