5.13.4.5 ERROR FRAME
The ERROR FRAME consists of two different fields. The first field is given by the super-position
of ERROR FLAG contributed from different stations. The following second field is the ERROR
DELIMITER.
There are 2 forms of ERROR FLAG: an ACTIVE ERROR FLAG and a PASSIVE ERROR FLAG.
The ACTIVE ERROR FLAG consists of six consecutive ‘dominant’ bits. The PASSIVE ERROR
FLAG consists of six consecutive ‘recessive’ bits unless it is overwritten by ‘dominant’ bits from
other nodes.
The ERROR DELIMITER consists of eight ‘recessive’ bits. After transmission of an ERROR
FLAG, each station sends ‘recessive’ bits and monitors the bus until it detects a ‘recessive’ bit.
Afterwards it starts transmitting seven more ‘recessive’ bits.
