Notes:

1. Addresses are Amax:A0 in word mode; Amax:A-1 in byte mode. Sector address are Amax: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, all the sectors remain protected. If WP#=VIH, all sector's 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).
