Interrupt Requests

There are four interrupt requests that are generated by the hardware LIN: Synch Break detection, Synch Break

generation completed, Synch Field measurement completed, and bus collision detection. These interrupts are

shared with timer RA.

Table 19.2 lists the Interrupt Requests of Hardware LIN.

Interrupt Requests of Hardware LIN

Interrupt Request

Status Flag

Cause of Interrupt

Synch Break detection

SBDCT

Generated when timer RA has underflowed after measuring

the “L” level duration of RXD0 input, or when a “L” level is

input for a duration longer than the Synch Break period

during communication.

Synch Break generation

completed

Generated when “L” level output to TXD0 for the duration set

by timer RA completes.

Synch Field

measurement completed

SFDCT

Generated when measurement for 6 bits of the Synch Field

by timer RA is completed.

Bus collision detection

BCDCT

Generated when the RXD0 input and TXD0 output values

differed at data latch timing while UART0 is enabled for

transmission.
