Field measurement
Bus collision detection
There are four interrupt requests generated by the hardware LIN: Synch Break detection, Completion of Synch
Break generation, Completion of Synch Field measurement, and bus collision detection. These interrupts are
shared with timer RA.
Table 27.2 lists the Hardware LIN Interrupt Requests.

Generated when the RXD0 input and TXD0 output values
Generated when timer RA underflows after the “L” level
duration for the RXD0 input is measured, or when a “L” level
is input for a duration longer than the Synch Break period
during communication.
Generated when a “L” level output to TXD0 for the duration
set by timer RA is completed.
Generated when measurement for 6 bits of the Lynch Field
by timer RA is completed.
