4.The sector protect and sector unprotect functions may also be implemented via programming equipment. See the
“Sector/Sector Block Protection and Unprotection” section.
5. 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.
