TABLE 4. MX29LV004C T/B COMMAND DEFINITIONS
Note:
1. ADI = Address of Device identifier; A1=0, A0 = 0 for manufacturer code,A1=0, A0 = 1 for device code. A2-A17=do
2. PA = Address of memory location to be programmed.
3. The system should generate the following address patterns: 555H or 2AAH to Address A11~A0.
4. For Sector Protect Verify operation:If read out data is 01H, it means the sector has been protected. If read out data

RA=Address of memory location to be read.
RD=Data to be read at location RA.
PD = Data to be programmed at location PA.
SA = Address of the sector to be erased.
