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 2)
DDI = Data of Device identifier : C2H for manufacture code, 4FH 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. 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.
4. Any number of CFI data read cycle are permitted.
