Final Data Sheet
Effect: permanent dominant signal for
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Action: disabling of the transmitter stage
Remarks: release of the transmitter stage only after transition into RxOnly mode (failure
diagnosis) and transition into normal mode.
Effect: internal RxD signal does not match signal at RxD pin because the RxD pin is pulled
to HIGH (permanent HIGH)
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Action: disabling of the receiver stage
Remarks: the flag is cleared by changing from RxOnly (failure diagnosis) into normal mode
or RxD gets dominant.
Effect: short circuit between RxD and TxD
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Action: disabling of the transmitter stage
Remarks: the flag is cleared by changing from RxOnly (failure diagnosis) into normal mode.
Effect: permanent dominant signal at the CAN bus for
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Action: none
Remarks: none
Effect: junction temperature at the driving stages exceeded
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Action: disabling of the transmitter stage
Remarks: the flag is cleared by changing from RxOnly (failure diagnosis) into normal mode
or RxD gets dominant. Bus only released after the next dominant bit in TxD.
