The architecture includes a 128 bits Protection
register that is divided into two 64-bits segments.
In the first one is written a unique device number,
while the second one is programmable by the us-
er. The user programmable segment can be per-
manently protected programming the bit 1 of the
Protection Lock Register (see protection register
and Security Block). The parameter block (# 0) is
a security block. It can be permanently protected
by the user programming the bit 2 of the Protection
Lock Register.
Block protection against Program or Erase pro-
vides additional data security. All blocks are pro-
tected and unlocked at Power-up. Instructions are
provided to protect or un-protect any block in the
application. A second register locks the protection
status while WP is low (see Block Locking descrip-
tion).
