The LTC bit can be used to set the LIN transceiver to a Listen-only mode. The transmitter
output stage is disabled in this mode.
When leaving Active mode the LIN transmitter is disabled and the LIN receiver is
monitoring the LIN-bus for a valid wake-up.
Off-line mode is the low-power mode of the LIN transceiver. The LIN transceiver is
disabled to save supply current. Pin RXDL reflects any wake-up event at the LIN-bus.
For a remote wake-up via LIN a LIN-bus signal is required as shown in
The RTLIN pin is in one of 3 different states: RTLIN = on, RTLIN = off or RTLIN = 75 μA;
