Sector/Sector Block Protection and
Unprotection
(Note: For the following discussion, the term “sector”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see Tables
8 and 9).
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both pro-
gram and erase operations in previously protected
sectors. Sector protection/unprotection can be imple-
mented via two methods.
Table 8.
Top Boot Sector/Sector Block Addresses
for Protection/Unprotection
Table 9.
Addresses for Protection/Unprotection
Bottom Boot Sector/Sector Block
The primary method requires V
ID
on the RESET# pin
only, and can be implemented either in-system or via
programming equipment. Figure 2 shows the algo-
rithms and Figure 25 shows the timing diagram. This
method uses standard microprocessor bus cycle tim-
ing. For sector unprotect, all unprotected sectors must
first be protected prior to the first sector unprotect
write cycle.
