Notes:

1. Address are A21:A1 in word mode; A21:A0 in byte mode. Sector addresses are A21:A14 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, all the sectors remain protected. If WP#=VIH, all sectors 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 Table 3 and Figure 15).
