Wait State Decoding Addresses:
A14, A13, A12 = “111” Ÿ Reserved
A14, A13, A12 = “110” Ÿ Reserved
A14, A13, A12 = “101” Ÿ 5 programmed, 7 total
A14, A13, A12 = “100” Ÿ 4 programmed, 6 total
A14, A13, A12 = “011” Ÿ 3 programmed, 5 total
A14, A13, A12 = “010” Ÿ 2 programmed, 4 total
A14, A13, A12 = “001” Ÿ 1 programmed, 3 total
A14, A13, A12 = “000” Ÿ 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”.
