A6, A4, A2, A0, M6, M4, M2, M0

IO1 = A23, A21, A19, A17, A15, A13, A11, A9

A7, A5, A3, A1, M7, M5, M3, M1

3. Quad Output Data

IO0 = (D4, D0, …..)

IO1 = (D5, D1, …..)

IO2 = (D6, D2, …..)

IO3 = (D7, D3,…..)

4. Quad Input Address

IO0 = A20, A16, A12, A8,

A4, A0, M4, M0

IO1 = A21, A17, A13, A9,

A5, A1, M5, M1

IO2 = A22, A18, A14, A10, A6, A2, M6, M2

IO3 = A23, A19, A15, A11, A7, A3, M7, M3

5. Fast Read Quad I/O Data

IO0 = (x, x, x, x, D4, D0,

…)

IO1 = (x, x, x, x, D5, D1,

…)

IO2 = (x, x, x, x, D6, D2,

…)

IO3 = (x, x, x, x, D7, D3,

…)

6. Fast Word Read Quad I/O Data

IO0 = (x, x, D4, D0,

…)

IO1 = (x, x, D5, D1,

…)

IO2 = (x, x, D6, D2,

…)

IO3 = (x, x, D7, D3,

…)

7. Fast Word Read Quad I/O Data: the lowest address bit must be 0.
