Note:

1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A19=do not care.

(Refer to table 2)

DDI = Data of Device identifier : C2H for manufacture code, 38H 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 to be erased.

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.
