NOTES:
3. Signal at 82C84A or 82C88 shown for reference only.
4. Setup requirement for asynchronous signal only to guarantee recognition at next CLK.
5. Applies only to T2 state (8ns into T3).
6. The 80C88 actively pulls the RQ/GT pin to a logic one on the following clock low time.
7. Status lines return to their inactive (logic one) state after CLK goes low and READY goes high.
