programmable wait value and the wait cycles controlled by the WAIT pin.
wait states will be inserted in the bus cycle. If wait insertion is controlled by the WAIT pin, wait states might not be
inserted at the expected timing. In this case, adjust the insertion timing by specifying a programmable wait value.
Wait cycles are inserted as the result of an OR operation between the wait cycles specified by the set
For example, if the timing of the programmable wait and the WAIT pin signal is as shown in the Figure 5-3, three
