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

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,…..)
