1.4 Address Map

The following figure is a map of the MCU internal addresses. The RAM array is positioned by the base

address registers in the associated RAM control block. Unimplemented blocks are mapped externally.

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 lines and 16 data lines.
