Note:
Functional Description and Application Information
When the under-voltage condition (LVI) is gone, the LIN will start operating when Tx is in a recessive state or on the next dominant
to recessive transition.

LIN - Over-temperature Interrupt Enable
LIN - Over-temperature condition present. LIN driver is shut down. Reading this bit will clear the LINOT interrupt flag.
LIN - Receiver (Rx) Status.
0 - LIN Bus Dominant
1 - LIN Bus Recessive
LIN - Direct Transmitter Control. The inverted signal is OR
0 - Transmitter not controlled
1 - Transmitter Dominant
LIN - Low Voltage Shutdown Disable (J2602 Compliance Control)
0 - LIN will be set to recessive state in case of VS1 under-voltage condition
1 - LIN will stay functional even with a VS1 under-voltage condition
