Bus collision detection
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 17.2 lists the Interrupt Requests of Hardware LIN.

Generated when the RXD0 input and TXD0 output values
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.
Generated when “L” level output to TXD0 for the duration set
by timer RA completes.
Generated when measurement for 6 bits of the Synch Field
by timer RA is completed.
differed at data latch timing while UART0 is enabled for
transmission.
