FUNCTIONAL DEVICE OPERATIONS
LOGIC COMMANDS AND REGISTERS
LIN Control Register - LINCR
This register controls the LIN physical interface block. Writing
the LIN Control Register (LINCR) returns the LIN Status
Register (LINSR).
Table 45. LIN Control Register - $4
LIN Status Register - LINSR
This register returns the status of the LIN physical interface
block and is also returned when writing to the LIN Control
Register (LINCR).

POR, Reset POR, Reset mode,
mode or ext_reset or LIN POR
ext_reset failure gone*
* LIN failure gone: if LIN failure (overtemp, TxD/RxD short) was set, the flag
resets automatically when the failure is gone.
LDVS - LIN Dominant Voltage Select
This write-only bit controls the LIN Dominant voltage:
1 = LIN Dominant Voltage = V LIN_DOM_1 (1.7 V typ)
0 = LIN Dominant Voltage = V LIN_DOM_0 (1.1 V typ)
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
Table 46. LIN Slew-rate Control
This read-only bit indicates a short-circuit condition on RXD
(shorted either to 5.0V or to Ground). The short-circuit delay
must be 8μs worst case to be detected and to shutdown the
driver. To clear this bit, it must be read after the condition is
gone (transition detected on RXD). The LIN driver is
automatically re-enabled once the condition is gone.
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 Shutdown
This read-only bit signals that the LIN transceiver was shut-
down 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

Fast Slew-Rate (up to 100 kb/s)
Reserved
LINOC - LIN Driver Over-current Shutdown
This read-only bit signals an over-current condition occurred
on the LIN pin. The LIN driver is not shut down but an IRQ is
generated. To clear this bit, it must be read after the condition
is gone.
1 = LIN over-current shutdown
0 = None
