Note:

1. ADI = Address of Device identifier; A1=0,A0 =0 for manufacture code,A1=0, A0 =1 for device code (Refer to Table

3).

DDI = Data of Device identifier : C2H for manufacture code, 36H/37H 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 to the sector to be erased.

3. The system should generate the following address patterns: 555H or 2AAH to Address A0~A10.

Address bit A11~A17=X=Don't care for all address commands except for Program Address (PA) and Sector

Address (SA). Write Sequence may be initiated with A11~A17 in either state.

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

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