FLAGS AND DEVICE STATUS
LIN/1/2
LIN/1/2 bus
dom clamp
Description
Report that the LIN/1/2 bus is dominant for a time longer than tDOM
Set / Reset condition
Set: Bus dominant clamp failure detected. Reset: failure recovered and flag read (SPI)
LIN/1/2 State
Description
Report real time LIN interface TXD/RXD mode. 1 if LIN is in TXD/RXD mode. 0 is LIN is not in TXD/
RXD mode.
Set / Reset condition
Set: LIN in TXD RXD mode. Reset: LIN not in TXD/RXD mode. LIN not in TXD/RXD mode by SPI
command (ex LIN set in Sleep mode) or following a failure event (ex: TxL Dominant). Flag read SPI
command (0x2780 or 0x2980) do not clear it, as it is “real time” flag.
LIN/1/2 WU
Description
Report real time LIN Wake-up receiver state. 1 if LIN Wake-up is enable, 0 if LIN Wake-up is disable
(means LIN signal will not be detected and will not Wake-up the device).
Set / Reset condition
Set: LIN WU enable (LIN interface set in Sleep mode Wake-up enable). Reset: LIN Wake-up disable
(LIN interface set in Sleep mode Wake-up disable). Flag read SPI command (0x2780 or 0x2980) do
not clear the flag, as it is “real time” information.
LIN/1/2
Wake-up
Description
Report that Wake-up source is LIN/1/2
Set / Reset condition
Set: after LIN/1/2 wake detected. Reset: Flag read (SPI)
LIN/1/2 Term
short to GND
Description
Report LIN/1/2 short to GND failure
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
LIN/1/2
overtemp
Description
Report that the LIN/1/2 interface has reach overtemperature threshold.
Set / Reset condition
Set: LIN/1/2 thermal sensor above threshold. Reset: sensor below threshold and flag read (SPI)
RXD-L/1/2
low
Description
Report that RXD/1/2 pin is shorted to GND.
Set / Reset condition
Set: RXD low failure detected. Reset: failure recovered and flag read (SPI)
RXD-L/1/2
high
Description
Report that RXD/1/2pin is shorted to recessive voltage.
Set / Reset condition
Set: RXD high failure detected. Reset: failure recovered and flag read (SPI)
TXD-L/1/2
dom
Description
Report that TXD/1/2 pin is shorted to GND.
Set / Reset condition
Set: TXD low failure detected. Reset: failure recovered and flag read (SPI)
