10.1 Features
The serial interface function provides three types of serial interfaces combining a total of six transmit/receive
channels. All six channels can be used simultaneously.
The three interface formats are as follows.
(1) Asynchronous serial interfaces (UART0 to UART2): 3 channels
(2) Clocked serial interfaces (CSI0, CSI1): 2 channels
(3) FCAN controller: 1 channel
Remark
For details about the FCAN controller, refer to CHAPTER 11 FCAN CONTROLLER.
UART0 to UART2, whereby one byte of serial data is transmitted/received following a start bit, support full-duplex
communication. In the UART1 and UART2 interfaces, one higher bit is added to 8 bits of transmit/receive data,
enabling communication using 9-bit data.
CSI0 and CSI1 perform data transfer according to three types of signals, namely serial clocks (SCK0, SCK1), serial
inputs (SI0, SI1), and serial outputs (SO0, SO1) (3-wire serial I/O).
FCAN conforms to CAN specification Ver. 2.0 PartB active, and provides a 32-message buffer.
