12.8 Operation of LIN communication
12.8.1 LIN transmission
In UART sending, UART0 supports LIN communication.
LIN sends channel 0 using unit 0.

Data phase
Normal-phase output (default: high).
Inverting output (default: low).
Parity bits
No parity bits.
Stop bit
Appending 1 bit.
Data direction
LSB takes precedence
Note It must be used within the range of peripheral functional characteristics that meet this condition and meet the
electrical characteristics (refer to the data sheet), and 2.4/9.6/19.2kbps are often used in LIN communication.
