Signal Descriptions

This chapter describes the MC68VZ328’s input and output signals, which are organized into functional
groups, as illustrated in Figure 2-1 on page 2-2. The MC68VZ328 uses a standard M68000 bus to
communicate with on-chip and external peripherals. This single continuous bus exists both on and off the
chip. CPU read cycles to internal memory-mapped registers of the device are invisible on the external bus,
but write cycles to internal or external memory-mapped locations are visible.
