Synch Break Detection

Synch Field Measurement
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, and bus collision detection. These interrupts are shared with the
timer RA interrupt.
Table 17.2 lists the Interrupt Requests of Hardware LIN.

Generated when timer RA has underflowed after measuring
the low level duration of RXD0 input, or when a low-level
signal is input for a duration longer than the Synch Break
period during communication.
Generated when timer RA has completed outputting a low-
level signal to TXD0 for set period.
Generated when measurement for 8 bits of the Synch Field
by timer RA is completed.
Generated when the RXD0 input and TXD0 output values
differed at data latch timing while UART0 is enabled for
transmission.
