Section 22 Electrical Characteristics
22.3.5 I/O Port Timing
Table 22.7 shows I/O port timing.
Table 22.7 I/O Port Timing
Conditions: V_CC = 4.0 V to 5.5 V, AV_CC = 4.0 V to 5.5 V, V_SS = PLLV_SS = AV_SS = 0 V, T_a = –20°C
to +75°C (Standard product)*, T_a = –40°C to +85°C (Wide temperature-range
product)*.

[Operating precaution]
The port input signals are asynchronous. They are, however, considered to have been
changed at CK clock falling edge with two-state intervals shown in figure 22.11. If the
setup times shown here are not observed, recognition may be delayed until the clock
falling two states after that timing.
Note: * See page 2 for correspondence of the standard product, wide temperature-range
product, and product model name.
