9.2
DiskOnChip G4 uses a NOR-like interface that can easily be connected to any microprocessor bus.
With a standard interface, it requires 13 address lines, 8 data lines and basic memory control signals
(CE#, OE#, WE#), as shown in Figure 13 below. Typically, DiskOnChip G4 can be mapped to any
free 8KB memory space.

When used as a boot device, DiskOnChip G4 eliminates the need for a dedicated boot ROM/NOR device.
(*) Address A0 is multiplexed with the DPD signal.
