FIGURE 25. BUS TIMING - MAXIMUM MODE SYSTEM (USING 82C88) (Continued)
NOTES:
22. Signals at 82C84A or 82C86 are shown for reference only.
23. The issuance of the 82C88 command and control signals (MRDC, MWTC, AMWC, IORC, IOWC, AIOWC, INTA and DEN) lags the active
high 82C88 CEN.
24. Status inactive in state just prior to T4.
25. Cascade address is valid between first and second INTA cycles.
26. Two INTA cycles run back-to-back. The 80C88 local ADDR/DATA bus is floating during both INTA cycles. Control for pointer address is
shown for second INTA cycle.
