NOTE:
1. Dual Output data
IO0 = (D6, D4, D2, D0)
IO1 = (D7, D5, D3, D1)
2. Dual Input Address
IO0 = A22, A20, A18, A16, A14, A12, A10, A8
IO1 = A23, A21, A19, A17, A15, A13, A11, A9
A6, A4, A2, A0, M6, M4, M2, M0
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
