Notes
1.
Addresses are AMax:A0 in word mode.
2.
If WP# = VIL, on the outermost sector remians protected. If WP# = VIH, the outermost secotr is unprotected. WP# has an internal pull-up; when uconnected, WP# is a VIH. All sectors are
unprotected wen shipped from the factory ( The Secured Silicon Sector can be factory protected depending on version ordered.)
3.
DIN or DOUT as required by command sequence, data polling, or sector protect algorithm.
