AC CHARACTERISTICS
Wait State Decoding Addresses:
A14, A13, A12 = “111” ⇒ Reserved
A14, A13, A12 = “110” ⇒ Reserved
A14, A13, A12 = “101” ⇒ 5 programmed, 7 total
A14, A13, A12 = “100” ⇒ 4 programmed, 6 total
A14, A13, A12 = “011” ⇒ 3 programmed, 5 total
A14, A13, A12 = “010” ⇒ 2 programmed, 4 total
A14, A13, A12 = “001” ⇒ 1 programmed, 3 total
A14, A13, A12 = “000” ⇒ 0 programmed, 2 total
Note: Figure assumes address D0 is not at an address boundary, active clock edge is rising, and wait state is set to “101”.
