USER’S MANUAL
The intermodule bus (IMB) is a standardized bus developed to facilitate both design
and operation of modular microcontrollers. It contains circuitry to support exception
processing, address space partitioning, multiple interrupt levels, and vectored inter-
rupts. The standardized modules in the MCU communicate with one another through
the IMB. The IMB in the MCU uses 24 address and 16 data lines.
Figure 3-1 is a functional diagram of the MCU. There is not a one-to-one correspon-
dence between location and size of blocks in the diagram and location and size of in-
tegrated-circuit modules. Figure 3-2 shows the MC68336 pin assignment package;
Figure 3-3 shows the MC68376 pin assignment package. Note that the MC68376 is
a pin-compatible upgrade for the MC68336 that provides a CAN protocol controller
and an 8-Kbyte masked ROM module. Both devices use a 160-pin plastic surface-
mount package. Refer to B.1 Obtaining Updated MC68336/376 Mechanical Infor-
mation for package dimensions. Refer to subsequent paragraphs in this section for
pin and signal descriptions.
• Full implementation of CAN protocol specification, version 2.0 A and B
• 16 receive/transmit message buffers of 0 to 8 bytes data length
• Global mask register for message buffers 0 to 13
• Independent mask registers for message buffers 14 and 15
• Programmable transmit-first scheme: lowest ID or lowest buffer number
• 16-bit free-running timer for message time-stamping
• Low power sleep mode with programmable wake-up on bus activity
