Notes:

1. All sectors will be unprotected if WP#/ACC=Vhv.

2. The two outmost boot sectors are protected if WP#/ACC=Vil.

3. When WP#/ACC = Vih, the protection conditions of the two outmost boot sectors depend on previous

protection conditions."Sector/Sector Block Protection and Unprotection" describes the protect and unprotect

method.

4. Q0~Q15 are input (DIN) or output (DOUT) pins according to the requests of command sequence, sector

protection, or data polling algorithm.

5. In Word Mode (Byte#=Vih), the addresses are AM to A0.

In Byte Mode (Byte#=Vil), the addresses are AM to A-1 (Q15).

6. AM: MSB of address.
