The LIN receiver is enabled to receive messages if both the RXFUNC bit and the RXENA bit are set to 1. If the RXFUNC bit is not set, the LINRX pin functions as a general-purpose I/O pin rather than as a LIN function pin.
The IDRXFLAG in the SCIFLR register is set after a valid LINID is received with an RX Match. An ID interrupt is then generated, if enabled.
