Note: * The

RES, NMI, IRQ7, IRQ6, and IRQ3 to IRQ0 signals are input asynchronously. If the

setup time indicated is maintained, the clock rise (in the case of

RES) or fall (in the case of

NMI,

IRQ7, IRQ6, and IRQ3 to IRQ0) will be recognized as a change in level. If the setup

time indicated is not maintained, the change may not be recognized until the next clock rise

or fall.
