Frame Formats
(Continued)
DS100044-21
DS100044-22
A remote frame is identical to a data frame, except that the RTR bit is “recessive”, and there is no data field.
IDE = Identifier Extension Bit
The IDE bit in the standard format is transmitted “dominant”, whereas in the extended format the IDE bit is “recessive” and the id is expanded to 29 bits.
r = recessive
d = dominant
