TXD Terminal
of the LIN transmitter (see
LOW, the LIN terminal is low (dominant state). When TXD is
HIGH, the LIN output MOSFET is turned off (recessive state).
The TXD terminal has an internal pullup current source in
order to set the LIN bus to recessive state in the event, for
instance, the microcontroller could not control it during
system power-up or power-down.
RXD Terminal
reports the state of the LIN bus voltage. LIN HIGH (recessive
state) is reported by a high level on RXD, LIN LOW (dominant
state) by a low level on RXD.
