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, D9H/DFH(x8) and 22D9H/22DFH(x16) 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 A10~A0 in word mode/
AAAH or 555H to Address A10~A-1 in byte mode.
Address bit A11~A15=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A11~A15 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.
