A CAN data frame consists of the following fields:
! Start of Frame (SOF)
! Arbitration Field + Extended Arbitration
! Control Field
! Data Field
! Cyclic Redundancy Check Field (CRC)
A remote frame is comprised of the following fields, which is
the same as a data frame (see CAN Frame Fields on page
113) except for the data field, which is not present.
! Start of Frame (SOF)
! Arbitration Field + Extended Arbitration
! Control Field
! Cyclic Redundancy Check Field (CRC)
! Acknowledgment field (ACK)
! End of Frame (EOF)
Note that the DLC must have the same value as the corre-
sponding data frame to prevent contention on the bus. The
RTR bit is “recessive”.
