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
SCK pin
Four interrupt sources
Choice of LSB-first or MSB-first transfer
Module stop mode can be set
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
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 interrupts can activate the data
transfer controller (DTC) to execute data transfer
Can be selected regardless of the communication mode * (except in the case of
asynchronous mode bit data)
As the initial setting, SCI operation is halted. Register access is enabled by exiting module
stop mode.
