Notes:

1. Address are A21:A0 in word mode; A21:A-1 in byte mode. Sector addresses are A21:A15 in both modes.

2. The sector group protect and chip unprotect functions may also be implemented via programming equipment. See

the "Sector Group Protection and Chip Unprotect" section.

3. If WP#=VIL, the first sectors remain protected. If WP#=VIH, the highest or lowest sector protection depends on

whether they were last protected or unprotect using the method described in "Sector/ Sector Block Protection and

Unprotect".

4. DIN or DOUT as required by command sequence, Data# polling or sector protect algorithm (see Figure 15).
