Notes:
1. If WP#/ACC =
V
IL
B
, the two outermost boot sectors remain protected. If WP# / ACC =
V
IH
B
, the outermost boot sector
protection depends on whether they were last protected or unprotected. If WP#/ACC =
V
HH
B
, all sectors will be
unprotected.
2. Please refer to “Sector/Sector Group Protection & Chip Unprotection”, Flowchart 7a and Flowchart 7b.
