PD = Program Data for location PA. Data latches on rising edge of WE# or
CE# pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or erased.
Address bits A21–A15 uniquely select any sector.
WBL = Write Buffer Location. Address must be within same write buffer page
as PA.
BC = Byte Count. Number of write buffer locations to load minus 1.
