Write Protect (WP#)
The Write Protect function provides a hardware
method of protecting the 16 Kbyte boot sector from
erasure without using V
If the system asserts V
disables erase functions for the 16 Kbyte boot sector
(SA34 for top boot device and SA0 for bottom boot de-
vice) independently of whether those sectors were
protected or unprotected using the method described
in
If the system asserts V
reverts to whether the 16 Kbyte boot sector was previ-
ously set to be protected or unprotected using the
method described in

Temporary Sector Unprotect
This feature allows temporary unprotection of previ-
ously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the RE-
SET# pin to V
sectors can be programmed or erased by selecting the
sector addresses. However, note that the boot sector is
still protected from erasure only if WP# is asserted low.
Once V
viously protected sectors are protected again.
