I/O Port Timing

Table 24.11 shows I/O port timing.

Table 24.11 I/O Port Timing

Conditions: V

CC = PLLVCC = 3.3 V ±0.3 V, PVCC1 = 5.0 V ±0.5 V, PVCC2 = 5.0 V ± 0.5 V,

CC = 5.0 V ±0.5 V, AVref = 4.5 V to AVCC, VSS = PLLVSS = AVSS = 0 V,

a = –40°C to 85°C.

When writing or erasing flash EEPROM, T

a = –40°C to 85°C.

[Operating precautions]

The operation guaranteed voltage range of power supply PV

CC1 in MCU single-chip mode is 5.0 V

±0.5 V. Do not use a voltage outside this range.

*1 The port input signals are asynchronous, but judged to have been changed at CK clock rise

with two-state intervals shown in figure 24.13. If the setup times shown here are not provided,

recognition is delayed until the clock rise two states after that timing.
