(7) 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,…)
(8) Fast Word Read Quad I/O Data: the lowest address bit must be 0.
(9) Security Registers Address:
Security Register1: A23-A16=00H, A15-A9=0001000b, A8-A0= Byte Address;
Security Register2: A23-A16=00H, A15-A9=0010000b, A8-A0= Byte Address;
Security Register3: A23-A16=00H, A15-A9=0011000b, A8-A0= Byte Address.
(10) 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, W7, x)
(11) Address, Continuous Read Mode bits, Dummy bits, Manufacture ID and Device ID
