This functionality must not be used for new designs, as the
M25PE80 delivered from Feb 2007 will not offer this functionality.
The write lock and lock down bits cannot be changed. Once a ‘1’
is written to the lock down bit it cannot be cleared to ‘0’ except by
a reset or power-up.

The write lock and lock down bits can be changed by writing new
values to them (default value).
