Notes: *1 SH7042/43 ZTAT (excluding A mask) are 3.2V.

*2 The

RES, MRES, NMI, BREQ, and IRQ7–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, MRES, BREQ) or clock fall (for NMI and

IRQ7–IRQ0). If the setup times are not provided, recognition is delayed until the next

clock rise or fall.
