FIGURE 7. BUS TIMING - MINIMUM MODE SYSTEM

NOTES:

1. All signals switch between VOH and VOL unless otherwise specified.

2. RDY is sampled near the end of T2, T3, TW to determine if TW machines states are to be inserted.

3. Two INTA cycles run back-to-back. The HS-80C86RH local ADDR/DATA bus is inactive during both INTA cycles. Control signals are

shown for the second INTA cycle.

4. Signals at HS-82C85RH are shown for reference only.

5. All timing measurements are made at 1.5V unless otherwise noted.
