Flag
Report real time CAN bus driver state: 1 if Driver is enable, 0 if driver disable
Set: CAN driver is enable. Reset: CAN driver is disable. Driver can be disable by SPI command (ex
CAN set in RxD only mode) or following a failure event (ex: TxD Dominant). Flag read SPI command
(0x2180) do not clear the flag, as it is “real time” information.
Report real time CAN bus receiver state: 1 if Enable, 0 if disable
Set: CAN bus receiver is enable. Reset: CAN bus receiver is disable. Receiver disable by SPI
command (ex: CAN set in sleep mode). Flag read SPI command (0x2180) do not clear the flag, as it
is “real time” information.
Report real time CAN bus wake up receiver state: 1 if WU receiver is enable, 0 if disable
Set: CAN wake up receiver is enable. Reset: CAN wake up receiver is disable. Wake up receiver is
controlled by SPI, and is active by default after device Power ON. SPI command (0x2180) do not
change flag state.
Report that wake-up source is CAN
Set: after CAN wake detected. Reset: Flag read (SPI)
Report that the CAN interface has reach over-temperature threshold.
Set: CAN thermal sensor above threshold. Reset: thermal sensor below threshold and flag read (SPI)
Report that RxD pin is shorted to GND.
Set: RxD low failure detected. Reset: failure recovered and flag read (SPI)
Report that RxD pin is shorted to recessive voltage.
Set: RxD high failure detected. Reset: failure recovered and flag read (SPI)
Report that TxD pin is shorted to GND.
Set: TxD low failure detected. Reset: failure recovered and flag read (SPI)
Report that the CAN bus is dominant for a time longer than t
Set: Bus dominant clamp failure detected. Reset: failure recovered and flag read (SPI)
Report that the CAN current is above CAN over-current threshold.
Set: CAN current above threshold. Reset: current below threshold and flag read (SPI)
Report that the CAN failure detection has not yet identified the bus failure
Set: bus failure pre detection. Reset: CAN bus failure recovered and flag read
Report that the CAN failure detection has identified the bus failure
Set: bus failure complete detetction.Reset: CAN bus failure recovered and flag read
Report CAN L short to V
Set: failure detected. Reset failure recovered and flag read (SPI)
Report CANL short to VDD
Set: failure detected. Reset failure recovered and flag read (SPI)
Report CAN L short to GND failure
Set: failure detected. Reset failure recovered and flag read (SPI)
Report CAN H short to V
Set: failure detected. Reset failure recovered and flag read (SPI)
Report CANH short to VDD
Set: failure detected. Reset failure recovered and flag read (SPI)
Report CAN H short to GND failure
Set: failure detected. Reset failure recovered and flag read (SPI)
