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, the two outermost boot sectors remain protected. If WP#=VIH, the two outermost boot sector protec-

tion 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).
