SERIAL PERIPHERAL INTERFACE
FLAGS AND DEVICE STATUS
CAN
CAN driver
state
Description
Report real time CAN bus driver state: 1 if Driver is enable, 0 if driver disable
Set / Reset condition
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.
CAN receiver
state
Description
Report real time CAN bus receiver state: 1 if Enable, 0 if disable
Set / Reset condition
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.
CAN WU
enable
Description
Report real time CAN bus Wake-up receiver state: 1 if WU receiver is enable, 0 if disable
Set / Reset condition
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.
CAN
Wake-up
Description
Report that Wake-up source is CAN
Set / Reset condition
Set: after CAN wake detected. Reset: Flag read (SPI)
CAN
Overtemp
Description
Report that the CAN interface has reach overtemperature threshold.
Set / Reset condition
Set: CAN thermal sensor above threshold. Reset: thermal sensor below threshold and flag read (SPI)
RXD low(50)
Description
Report that RXD pin is shorted to GND.
Set / Reset condition
Set: RXD low failure detected. Reset: failure recovered and flag read (SPI)
Rxd high
Description
Report that RXD pin is shorted to recessive voltage.
Set / Reset condition
Set: RXD high failure detected. Reset: failure recovered and flag read (SPI)
TXD dom
Description
Report that TXD pin is shorted to GND.
Set / Reset condition
Set: TXD low failure detected. Reset: failure recovered and flag read (SPI)
Bus Dom
clamp
Description
Report that the CAN 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)
CAN
Overcurrent
Description
Report that the CAN current is above CAN overcurrent threshold.
Set / Reset condition
Set: CAN current above threshold. Reset: current below threshold and flag read (SPI)
CAN_UF
Description
Report that the CAN failure detection has not yet identified the bus failure
Set / Reset condition
Set: bus failure pre detection. Reset: CAN bus failure recovered and flag read
CAN_F
Description
Report that the CAN failure detection has identified the bus failure
Set / Reset condition
Set: bus failure complete detetction.Reset: CAN bus failure recovered and flag read
CANL
to VBAT
Description
Report CAN L short to VBAT failure
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
CANL to VDD
Description
Report CANL short to VDD
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
CANL to GND Description
Report CAN L short to GND failure
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
CANH
to VBAT
Description
Report CAN H short to VBAT failure
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
CANH to VDD
Description
Report CANH short to VDD
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
CANH to
GND
Description
Report CAN H short to GND failure
Set / Reset condition
Set: failure detected. Reset failure recovered and flag read (SPI)
