PD = Data to be programmed at location PA. Data latches on the rising
edge of WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or
erased. Address bits A19–A12 uniquely select any sector.
BA = Address of the bank that is being switched to autoselect mode, is
in bypass mode, or is being erased.
