This asynchronous interface consists of 20 address lines, 32 data lines, and three chip-select lines. The chip-select lines are mapped to three external zones, Zones 0, 6, and 7. Each of the three zones can be programmed with a different number of wait states, strobe signal setup and hold timing and each zone can be programmed for extending wait states externally or not. The programmable wait state, chip-select and programmable strobe timing enables glueless interface to external memories and peripherals.
