Remark ISC0, ISC1: Bits 0 and 1 of the input switch control register (ISC) (see Figure 11-11)
The peripheral functions used in the LIN communication operation are shown below.
<Peripheral functions used>
External interrupt (INTP0); wakeup signal detection
Use: Detects the wakeup signal edges and detects start of communication.
16-bit timer/event counter 00 (TI000); baud rate error detection
Use: Detects the baud rate error (measures the TI000 input edge interval in the capture mode) by detecting the
Serial interface UART6
synchronous field (SF) length and divides it by the number of bits.
