The LIN transmitter is enabled if both the TXFUNC bit and the TXENA bit are set to 1. If the TXFUNC bit is not set, the LINTX pin functions as a general-purpose I/O pin rather than as a LIN function pin. Any value written to the TD0 before the TXENA bit is set to 1 is not transmitted. Both of these control bits allow for the LIN transmitter to be held inactive independently of the receiver.
The IDTXFLAG bit in the SCIFLR register is set after a valid LIN ID is received with a TX Match. An ID interrupt is then generated, if enabled.
