FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
* LIN failure gone: if LIN failure (over-temperature, TxD/
RxD short) was set, the flag resets automatically when
the failure gone.
J2602 Compliant Low Voltage Shutdown
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 and 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 16.
Table 16. LIN Slew Rate Control
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.
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 8.0 s 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 pin). The LIN
driver is automatically re-enabled once the condition is gone.
1 = RxD short circuit condition.
0 = None.
TXDOM - Tx Permanent Dominant
This read-only bit signals the detection of a TxD pin stuck
at dominant (Ground) condition and the resultant shut-down
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
High Side Control Register - HSCR
This register controls the operation of the High Side
drivers. Writing to this register returns the High Side Status
Register HSSR.
