PD = Program Data (DQ15:DQ0) written to location PA. Data latches on the rising edge of WE# or CE# pulse, whichever happens first. RA = Read Address (A18:A-1). RD = Read Data (DQ15:DQ0) from location RA. SA = Sector Address (A18:A11) for verifying (in autoselect mode), erasing, or applying security commands WD = Write Data.
