NOTE:
(1) Write Status Register (01H)
Normally, Write Status Register (01H) is used to write both lower status register and higher status register;
However, if CS# goes up at the eighth bit of the data byte, the data byte would be written as lower byte of
status register, without changing the higher byte of status register.
(2) Dual Output data
IO0 = (D6, D4, D2, D0)
IO1 = (D7, D5, D3, D1)
(3) 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
(4) Quad Output Data
IO0 = (D4, D0, …..)
IO1 = (D5, D1, …..)
IO2 = (D6, D2, …..)
IO3 = (D7, D3,…..)
(5) 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
(6) 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,…)
