Figure 10. CAN 0 Controller Block Diagram
CAN Functional Description
The basic functions covered by the CAN controller
include the use of 11-bit standard or 29-bit extended
acceptance identifiers, as programmed by the C for
each message center, as shown in Figure 10. The CAN
unit stores up to 15 messages, with the standard 8-byte
data field in each message.
Each of the first 14 message centers is programmable
in either transmit or receive mode. Message center 15
is a receive-only message center with a buffer FIFO
arrangement to help prevent the inadvertent loss of
data when the C is busy and is not allowed time to
retrieve the incoming message prior to the acceptance
of a second message into message center 15.
Message center 15 also utilizes an independent set of
mask registers and identification registers, only applied
once an incoming message has not been accepted by
any of the first 14 message centers. A second filter test
is also supported for all message centers (1–15) to
allow the CAN controller to use two separate 8-bit
media masks and media arbitration fields to verify the
contents of the first 2 bytes of data of each incoming
