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, break field 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 RxD2 is measured in the capture mode.) 
 
Measured the low-level width, determine whether break field (BF). 
•  Channels 0 and 1 (UART2) of serial array unit 1 (SAU1)
