Note:

The

RES, NMI, IRQ7, IRQ6, and IRQ3 to IRQ0 signals are asynchronous inputs, but

when the setup times shown here are provided, the signals are considered to have

produced changes at clock rise (for

RES) or clock fall (for NMI, IRQ7, IRQ6, and IRQ3

IRQ0). If the setup times are not provided, recognition is delayed until the next clock

rise or fall.
