AC CHARACTERISTICS
Wait State Decoding Addresses:
A14, A13, A12 = “101”
A14, A13, A12 = “100”
A14, A13, A12 = “011”
A14, A13, A12 = “010”
A14, A13, A12 = “001”
A14, A13, A12 = “000”
Note: Figure assumes address D0 is not at an address boundary, active clock edge is rising, and wait state is set to “101”.
