RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA.
SD = Sector protection verify data. Output 01h at protected sector addresses and output 00h
at unprotected sector addresses.
The system should generate the following address patterns: 555h or 2AAh to addresses A10 to A0
