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”.
