11.6 Operation of UART (UART0, UART1, UART3) Communication
reception (RxD) lines. It transmits or receives data in asynchronization with the party of communication (by using an
internal baud rate). Full-duplex UART communication can be realized by using two channels, one dedicated to
transmission (even channel) and the other to reception (odd channel).

This is a start-stop synchronization function using two lines: serial data transmission (TxD) and serial data
[Data transmission/reception]
[Interrupt function]
[Error detection flag]
The LIN-bus is supported in UART3 (2, 3 channels of unit 1)
[LIN-bus functions]
UART0 uses channels 0 and 1 of SAU0.
UART1 uses channels 2 and 3 of SAU0.
UART3 uses channels 2 and 3 of SAU1.
Caution When using serial array units 0 and 1 as UARTs, the channels of both the transmitting side (even-
UART performs the following four types of communication operations.
Unit
• UART transmission
• UART reception
• LIN transmission (UART3 only) (See 11.6.3.)
• LIN reception (UART3 only)
• Data length of 5, 7, or 8 bits
• Select the MSB/LSB first
• Level setting of transmit/receive data and select of reverse
• Parity bit appending and parity check functions
• Stop bit appending
• Transfer end interrupt/buffer empty interrupt
• Error interrupt in case of framing error, parity error, or overrun error
• Framing error, parity error, or overrun error
• Wakeup signal detection
• Sync break field (SBF) detection
• Sync field measurement, baud rate calculation
number channel) and the receiving side (odd-number channel) can be used only as UARTs.
