5 MESSAGE VALIDATION
The point of time at which a message is taken to be valid, is different for the transmitter
and the receivers of the message.
Transmitter:
The message is valid for the transmitter, if there is no error until the end of END OF
FRAME. If a message is corrupted, retransmission will follow automatically and
according to prioritization. In order to be able to compete for bus access with other
messages, retransmission has to start as soon as the bus is idle.
Receivers:
The message is valid for the receivers, if there is no error until the last but one bit of
END OF FRAME. The value of the last bit of END OF FRAME is treated as ’don’t care’,
a dominant value does not lead to a FORM ERROR (cf. section 7.1).
