Section 16 Controller Area Network (HCAN)
Message Buffer Interface (MBI): The MBI, consisting of mailboxes and a local acceptance filter
mask (LAFM), stores CAN transmit/receive messages (identifiers, data, etc.). Transmit messages
are written by the CPU. For receive messages, the data received by the CDLC is stored
automatically.
Microprocessor Interface (MPI): The MPI, consisting of a bus interface, control register, status
register, etc., controls HCAN internal data, statuses, and so forth.
CAN Data Link Controller (CDLC): The CDLC performs transmission and reception of
messages conforming to the Bosch CAN Ver. 2.0B active standard (data frames, remote frames,
error frames, overload frames, inter-frame spacing), as well as CRC checking, bus arbitration, and
other functions.
16.1.3
Table 16-1 shows the HCAN’s pins.
When using HCAN pins, settings must be made in the HCAN configuration mode (during
initialization: MCR0 = 1 and GSR3 = 1).

Note: * The HCAN1 is not supported by the H8S/2635 Group.
A bus driver is necessary between the pins and the CAN bus. A HA13721 compatible model is
recommended.
