1. Overview

Communication

function

Serial communications

interfaces (SCIk, SCIh)

 4 channels

SCIk: SCI1, SCI5, SCI6

SCIh: SCI12

 SCIk, SCIh

Serial communications modes: Asynchronous, clock synchronous, and smart-card

interface

Multi-processor function

On-chip baud rate generator allows selection of the desired bit rate

Choice of LSB-first or MSB-first transfer

Average transfer rate clock can be input from TMR timers for SCI5, SCI6, and SCI12

Start-bit detection: Level or edge detection is selectable.

Simple I2C

Simple SPI

7, 8, 9-bit transfer mode

Bit rate modulation

Double-speed mode

Data match detection (SCI12 is not supported)

Event linking by the ELC (supported by SCI5 only)

RXD input signal select function (supported by SCI5 only)

 SCIk Only

Data match detection

Adjustment of the timing of sampling of the RXD signals

 SCIh Only

Supports the serial communications protocol, which contains the start frame and

information frame

Supports the LIN format
