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
