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.)
