12.7 LIN Communication Operation 
12.7.1 LIN transmission 
UART0 transmission supports LIN communication. 
For LIN transmission, channel 0 is used. 
UART UART0 
Support of LIN communication  Supported   
Target channel  Channel 0 
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
15
 × 128) [bps] 
Note 
Data phase  Non-reverse output (default: high level) 
Reverse output (default: low level) 
Parity bit  No parity bit 
Stop bit  Appending 1 bit 
Data direction  LSB first 
Note  Use this operation within a range that satisfies the conditions above and the peripheral functions characteristics in 
the electrical specifications (see CHAPTER 30 ELECTRICAL SPECIFICATIONS (A, G: T
A = -40 to +85°C) and 
CHAPTER 31 ELECTRICAL SPECIFICATIONS (G: TA = -40 to +105°C)). In addition, LIN communication is 
usually 2.4/9.6/19.2 kbps is often used.
