The peripheral functions used for the LIN communication operation are as follows.
<Peripheral functions used>
• External interrupt (INTP0); Wakeup signal detection
Usage: To detect an edge of the wakeup signal and the start of communication
• Channel 7 of timer array unit; Baud rate error detection and break field (BF) detection
Usage: To detect the length of the sync field (SF) and divide it by the number of bits in order to detect an error (The
interval of the edge input to RxD0 is measured in the capture mode.)
To measure a low-level width and determine whether the field is a break field (BF)
• Channels 0 and 1 (UART0) of serial array unit 0 (SAU0)
