23.3.10 AC Characteristics Measurement Conditions
• I/O signal reference level: VccQ/2 (VccQ = 3.3 ± 0.3 V, Vcc = 1.55 to 2.15 V)
• Input pulse level: Vss to 3.0 V (where RESETP, RESETM, ASEND0, IRLS3 to IRLS0, IRL3
to IRL0, ADTRG, PINT15 to PINT0, TRST, RxD1, CA, NMI, IRQ5–IRQ0, CKIO, and
MD5–MD0 are within Vss to Vcc)
• Input rise and fall times: 1 ns
