Section 13 Serial Communication Interface (SCI)
Rev. 6.00 Feb 22, 2005 page 436 of 1484
REJ09B0103-0600
Full-duplex communication capability
Choice of LSB-first or MSB-first transfer
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
Module stop mode can be set
One serial data transfer format
Data length
Receive error detection : Overrun errors detected
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
Can be selected regardless of the communication mode * (except in the case of
asynchronous mode 7-bit data)
Note: * Descriptions in this section refer to LSB-first transfer.
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
As the initial setting, SCI operation is halted. Register access is enabled by exiting module
stop mode
: 8 bits
