Note:

1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A17=do

not care.

(Refer to table 3)

DDI = Data of Device identifier : C2H for manufacture code, B5H/B6H (Top/Bottom) for device code.

X = X can be VIL or VIH

RA=Address of memory location to be read.

RD=Data to be read at location RA.

2. PA = Address of memory location to be programmed.

PD = Data to be programmed at location PA.

SA = Address of the sector to be erased.

3. The system should generate the following address patterns: 555H or 2AAH to Address A11~A0.

Address bit A12~A18=X=Don't care for all address commands except for Program Address (PA) and Sector

Address (SA). Write Sequence may be initiated with A12~A18 in either state.

4. For Sector Protect Verify operation:If read out data is 01H, it means the sector has been protected. If read out

data is 00H, it means the sector is still not being protected.
