Truth Table III — Interrupt Flag(1,4)
Waveform of Interrupt Timing(1)
NOTES:
1. All timing is the same for left and right ports. Port “A” may be either the left or right port. Port “B” is the port opposite from port “A”.
2. Refer to Interrupt Truth Table.
3. Timing depends on which enable signal (CE or R/W) is asserted last.
4. Timing depends on which enable signal (CE or R/W) is de-asserted first.
NOTES:
1. Assumes BUSYL = BUSYR =VIH.
2. If BUSYL = VIL, then no change.
3. If BUSYR = VIL, then no change.
4. INTL and INTR must be initialized at power-up.
5. A16x is a NC for IDT70V658, therefore Interrupt Addresses are FFFF and FFFE.
6. A16x and A15x are NC's for IDT70V657, therefore Interrupt Addresses are 7FFF and 7FFE.
