1.2 CAN Frame Format

CAN-FD frame formats are shown in Figure 1-2, Figure 1-3, Figure 1-4; bit value of 1 is regarded as recessive and a value of 0 is regarded as dominant.

CRC Cyclic redundancy check
  • IDE = recessive, indicates extended (29 bit) identifier; IDE = dominant, indicates standard (11 bit) identifier.
  • FDF = recessive, indicates CAN-FD format; FDF=dominant, indicates CAN frame
  • BRS=recessive, indicates bit-rate switching to a faster rate; BRS=dominant, indicates no change in rate
