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 provides storage for 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 designed as a receive-only message center with a
buffer FIFO arrangement to help prevent the inadver-
tent 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 indepen-
dent set of mask registers and identification registers,
which are only applied once an incoming message has
not been accepted by any of the first 14 message cen-
ters. A second filter test is also supported for all mes-
sage 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
