Note:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacture code,A1=0, A0 = 1 for device code. A2-A18=do not care.
(Refer to table 3)
DDI = Data of Device identifier : C2H for manufacture code, D6H/58H (x8) and 22D6H/2258H (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~A18=X=Don't care for all address commands except for Program Address (PA) and Sector
Address (SA). Write Sequence may be initiated with A11~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.
