15.8 LIN Communication Operation
15.8.1 LIN transmission
Of UART transmission, UART0 support LIN communication.
For LIN transmission, channel 0 of unit 0 is used.
UART UART0 UART1
Support of LIN communication Supported Not supported
Target channel Channel 0 of SAU0
−
Pins used TxD0
−
Interrupt INTST0
−
Transfer end interrupt (in single-transfer mode) or buffer empty interrupt (in continuous transfer
mode) can be selected.
Error detection flag None
Transfer data length 8 bits
Transfer rate Max. fMCK/6 [bps] (SDR00 [15:9] = 2 or more), Min. fCLK/(2 × 2
11
× 128) [bps]
Note
Data phase Forward output (default: high level)
Reverse output (default: low level)
Parity bit No parity bit
Stop bit Appending 1 bit
Data direction MSB or LSB first
Note Use this operation within a range that satisfies the conditions above and the AC characteristics in the electrical
specifications. The transfer rate of LIN communication is usually set to 2.4, 9.6, or 9.2 kbps.
