Note:
WR0 and WR1 output a low level as shown in the above timing chart when target data access is
performed. At all other times, these pins output a high level.
Remarks: 1.
The circles indicate the sampling timing when 0 is set for the programmable wait.
2.
The broken line indicates high impedance.
