4.
If WP#/ACC = V
IL
, the boot sectors will be protected. If WP#/ACC = V
IH
the boot sectors protection will be removed.
If WP#/ACC = V
ACC
(9V), the program time will be reduced by 40%.
5.
The sector protect and sector unprotect functions may also be implemented via programming equipment. See the
“
Sector/Sector Block Protection
and Unprotection
”
section.
6.
If WP#/ACC = V
, the two outermost boot sectors remain protected. If WP#/ACC = V
, 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.
