Notes:
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 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
Set Burst with Wrap Input
IO0 = x, x, x, x, x, x, W4, x
IO0 = A20, A16, A12, A8, A4, A0, M4, M0
IO1 = A21, A17, A13, A9, A5, A1, M5, M1
IO1 = x, x, x, x, x, x, W5, x
IO2 = A22, A18, A14, A10, A6, A2, M6, M2
IO2 = x, x, x, x, x, x, W6, x
IO3 = A23, A19, A15, A11, A7, A3, M7, M3
IO3 = x, x, x, x, x, x, x, x
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. 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. The lowest address bit must be 0. ( A0 = 0 )
8. The lowest 4 address bits must be 0. ( A0, A1, A2, A3 = 0 )
