UART0 uses channels 0 and 1.
Channel Used as CSI Used as UART
0 CSI00
UART0 (supporting LIN-
bus)
1 CSI01
Caution When using serial array unit as UARTs, the channels of both the transmitting side (even-number
channel) and the receiving side (odd-number channel) can be used only as UARTs.
UART performs the following four types of communication operations.
• UART transmission (See 12.6.1.)
• UART reception (See 12.6.2.)
• LIN transmission (See 12.7.1.)
• LIN reception (See 12.7.2.)
