Notes:
1. The address bits 0–7, 8–15, and 16–23 each share a single output enable. In this table, the output enables are
2. Direction on the data bus is controlled by a single output enable. It is shown in this table as being associated
3. MREQ,
shown to be associated with the least-significant bit that they control.
