1.5 Intermodule Bus

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 partition-

ing, multiple interrupt levels, and vectored interrupts. The standardized modules in the MCU communi-

cate with one another and with external components through the IMB. The IMB in the MCU uses 24

address and 16 data lines.
