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
synchronous field (SF) length and divides it by the number of bits.
• Serial interface UART6
