Section 12 Serial Communication Interface (SCI)
⢠Full-duplex communication capability
⯠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
⢠Choice of LSB-first or MSB-first transfer
⯠Can be selected regardless of the communication mode* (except in the case of
asynchronous mode 7-bit data)
⢠Built-in 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
SCK pin
⢠Four interrupt sources
⯠Four interrupt sourcesâtransmit-data-empty, transmit-end, receive-data-full, and receive
errorâthat can issue requests independently
⯠The transmit-data-empty and receive-data-full interrupts can activate the data transfer
controller (DTC) to execute data transfer
⢠Module stop mode can be set
⯠As the initial setting, SCI operation is halted. Register access is enabled by exiting module
stop mode
Note: * Descriptions in this section refer to LSB-first transfer.
