Note:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer 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, 22DA/DA(Top), and 225B/5B(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.
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.
5. Any number of CFI data read cycle are permitted.
