FIGURE 10. BUS TIMING - MAXIMUM MODE SYSTEM (USING 82C88)
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. Cascade address is valid between first and second INTA cycle.
4. Two INTA cycles run back-to-back. The HS-80C86RH local ADDR/DATA bus is inactive during both INTA cycles. Control for pointer ad-
dress is shown for the second INTA cycle.
5. Signals at HS-82C85RH or 82C88 are shown for reference only.
6. The issuance of the 82C88 command and control signals (MRDC, MWTC, AMWC, IORC, IOWC, AIOWC, INTA and DEN) lags the active
high 82C88 CEN.
7. All timing measurements are made at 1.5V unless otherwise noted.
8. Status inactive in state just prior to T4.
