The architecture includes a 128 bit Protection reg-
ister that is divided into two 64 bit segments. In the
first one is written a unique device number, while
the second one is programmable by the user. The
user programmable segment can be permanently
protected programming the bit 1 of the Protection
Lock Register (see protection register and Securi-
ty 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 Reg-
ister.
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).
