Notes:
1. Addresses are A20:A0 in word mode (BYTE#=V_IH) , A20:A-1 in byte mode (BYTE#=V_IL).
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector/Sector
Block Protection and Unprotection” section.
3. If WP#/ACC=V_IL, the two outermost boot sectors remain protected. If WP#/ACC=V_IH, the two outermost boot sector protection
depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and
Unprotection”. If WP#/ACC=V_HH, all sectors will be unprotected.
4. D_IN or D_OUT as required by command sequence, data polling, or sector protection algorithm.
