Flag
Report that the LIN1/2 bus is dominant for a time longer than t
Set: Bus dominant clamp failure detected. Reset: failure recovered and flag read (SPI)
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: 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.
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: 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.
Report that wake-up source is LIN1 or LIN2
Set: after LIN1 or LIN 2 wake detected. Reset: Flag read (SPI)
Report LIN term 1 or LIN term 2 short to GND failure
Set: failure detected. Reset failure recovered and flag read (SPI)
Report that the LIN1 or LIN 2 interface has reach over-temperature threshold.
Set: LIN1/2 thermal sensor above threshold. Reset: sensor below threshold and flag read (SPI)
Report that RxD1/2 pin is shorted to GND.
Set: RxD low failure detected. Reset: failure recovered and flag read (SPI)
Report that RxD1/2pin is shorted to recessive voltage.
Set: RxD high failure detected. Reset: failure recovered and flag read (SPI)
Report that TxD1/2 pin is shorted to GND.
Set: TxD low failure detected. Reset: failure recovered and flag read (SPI)
