LIN Active Indicator Bit.
0: No transmission activity detected on the LIN bus.
1: Transmission activity detected on the LIN bus.
Bus Idle Timeout Bit. (slave mode only)
0: The bus has not been idle for four seconds.
1: No bus activity has been detected for four seconds, but the bus is not yet in Sleep
mode.
Aborted Transmission Bit. (slave mode only)
0: The current transmission has not been interrupted or stopped. This bit is reset to 0
after receiving a SYNCH BREAK that does not interrupt a pending transmission.

bit (LIN0CTRL.7) has been set.
Data Request Bit. (slave mode only)
0: Data identifier has not been received.
1: Data identifier has been received.
Interrupt Request Bit.
0: An interrupt is not pending. This bit is cleared by setting RSTINT (LIN0CTRL.3)
1: There is a pending LIN0 interrupt.
Communication Error Bit.
0: No error has been detected. This bit is cleared by setting RSTERR (LIN0CTRL.2)
1: An error has been detected.
Wakeup Bit.
0: A wakeup signal is not being transmitted and has not been received.
1: A wakeup signal is being transmitted or has been received
Transmission Complete Bit.
