RXSHORT - RXD Pin Short-circuit
This read-only bit indicates a short-circuit condition on the
RXD pin (shorted either to 5.0 V or to Ground). The short-
circuit delay must be a worst case of 8μs to be detected and
to shut down the driver. To clear this bit, it must be read after
the condition is gone (transition detected on RXD pin). The
LIN driver is automatically re-enabled once the condition is
gone and TXD is high.
1 = RXD short-circuit condition.

gone*
* LIN failure gone: if LIN failure (overtemp, TXD/RXD short) was set,
the flag resets automatically when the failure is gone.
J2602 - LIN Dominant Voltage Select
This write-only bit controls the J2602 circuitry. If the circuitry
is enabled (bit sets to 0), the TXD-LIN-RXD communication
works down to the battery under-voltage condition is
detected. Below, the bus is in recessive state. If the circuitry
is disabled (bit sets to 1), the communication TXD-LIN-RXD
works down to 4.6 V (typical value).
0 = Enabled J2602 feature.
1 = Disabled J2602 feature.
RXONLY - LIN Receiver Operation Only
This write-only bit controls the behavior of the LIN transmitter.
In Normal mode, the activation of the RXONLY bit disables
the LIN transmitter. In case of a LIN error condition, this bit is
automatically set.
In Stop mode this bit disables the LIN wake-up functionality,
and the RXD pin will reflect the state of the LIN bus.
1 = only LIN receiver active (Normal mode) or LIN wake-up
disabled (Stop mode).
0 = LIN fully enabled.
LSRx - LIN Slew-Rate
TXDOM - TXD Permanent Dominant
This read-only bit signals the detection of a TXD pin stuck at
dominant (Ground) condition and the resultant shutdown in
the LIN transmitter. This condition is detected after the TXD
pin remains in dominant state for more than 1 second (typical
value).
To clear this bit, it must be read after TXD has gone high. The
LIN driver is automatically re-enabled once TXD goes High.
1 = TXD stuck at dominant fault detected.
0 = None.
LINOT - LIN Driver Over-temperature
This read-only bit signals that the LIN transceiver was
shutdown due to over-temperature. The transmitter is
automatically re-enabled after the over-temperature
condition is gone and TXD is high. The LINOT bit is cleared
after SPI read once the condition is gone.
1 = LIN over-temperature shutdown
0 = None
High Side Control Register - HSCR
This register controls the operation of the high side driver.
Writing to this register returns the High Side Status Register
(HSSR).

LIN Status Register - LINSR
This register returns the status of the LIN physical interface
block and is also returned when writing to the LINCR.

PWMHS1 - PWM Input Control Enable.
This write-only bit enables/disables the PWMIN input pin to
control the high side switch. The high side switch must be
enabled (HS1 bit).
1 = PWMIN input controls HS1 output.
0 = HS1 is controlled only by SPI.
