7.4.4.1 Wake Up Request (RXD)

When the TLIN829-Q1 encounters a wake up event from the LIN bus, RXD goes low and the device transitions to standby mode until EN is reasserted high and the device enters normal mode. Once the device enters normal mode, the RXD pin releases the wake up request signal and the RXD pin then reflects the receiver output from the LIN bus.
