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.

8. Security Registers Address:

Security Register1: A23-A16=00H, A15-A10=000100b, A9-A0= Byte Address;

Security Register2: A23-A16=00H, A15-A10=001000b, A9-A0= Byte Address;

Security Register3: A23-A16=00H, A15-A10=001100b, A9-A0= Byte Address.

9. Dummy bits and Wrap Bits

IO0 = (x, x, x, x, x, x, W4,x)

IO1 = (x, x, x, x, x, x, W5, x)

IO2 = (x, x, x, x, x, x, W6, x)

IO3 = (x, x, x, x, x, x, x, x)

10. Address, Continuous Read Mode bits, Dummy bits, Manufacture ID and Device ID

IO0 = (A20, A16, A12, A8, A4, A0,

M4, M0,

x, x, x, x,

MID4, MID0, DID4, DID0, …)

IO1 = (A21, A17, A13, A9, A5, A1,
