Final Data Sheet
Indicator: NERR = LOW in RxOnly mode
Remarks: Power-up flag is cleared when entering the normal mode
Task: to signalize a wake-up condition at the WK pin (filtering time
message (filtering time
Indicator: RxD or NERR = LOW in sleep/stand-by mode immediately after wake-up
Remarks: Flag is cleared on entering the RxOnly mode
Task: to distinguish between the two wake-up sources
Indicator: NERR = LOW in normal mode = wake-up via WK pin
Remarks: only available if the power-up flag is cleared. After four recessive to dominant
edges on TxD in normal mode, the flag is cleared. Leaving the normal mode clears the wake-
up source flag.
Task: to signalize a bus line short circuit condition to GND,
Indicator: NERR = LOW in normal mode
Remarks: flag is set after four consecutive recessive to dominant cycles on pin TxD when
trying to drive the bus dominant. The bus failure flag is cleared if the normal mode is
reentered or 4 recessive to dominant edges at TxD without failure condition.
Task: to signalize one of the five local failure conditions described in
and -Detection
Indicator: NERR = LOW in RxOnly mode (local failure flag is set)
Remarks: the flag is cleared when entering the normal mode from RxOnly mode or when RxD
is dominant while TxD is recessive.
