Serial Interface Function

13.1 Features

The serial interface function provides three types of serial interfaces combining a total of 9 transmit/
receive channels. All channels can be used simultaneously.
The three interface formats are as follows.

• Asynchronous serial interfaces (UART50, UART51): 2 channels

• Clocked serial interfaces (CSI00 to CSI02): 3 channels

• FCAN controller: 4 channels

Remark:

For details about the FCAN controller, refer to Chapter 13 FCAN Interface Function.

UART50 and UART51 transmit/receive 1-byte serial data following a start bit and support full-duplex
communication.
CSI00 to CSI02 perform data transfer according to three types of signals, namely serial clocks (SCK00
to SCK02), serial inputs (SI00 to SI02), and serial outputs (SO00 to SO02) (3-wire serial I/O).
FCAN conforms to CAN specification Version 2.0 Part B, and provides 64-message buffers.
