Table 26.9 shows I/O port timing.
Table 26.9 I/O Port Timing
Conditions: V
[Operating precautions]
The port input signals are asynchronous. They are, however, considered to have been changed at
CK clock fall with two-state intervals shown in figure 26.17. If the setup times shown here are not
observed, recognition may be delayed until the clock fall two states after that timing.
