Figure 13.7 Data Flow in Single Address Mode

Two kinds of transfer are possible in single address mode: (1) transfer between an external

device with DACK and a memory-mapped external device, and (2) transfer between an

external device with DACK and external memory. In both cases, only the external request

signal (DREQ) is used for transfer requests.
