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

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
This write-only bit controls the LIN driver slew-rate in
accordance with Table 18 .
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 8.0 μs 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.
0 = None.
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
