1. Any other combination of the Lock bits is not defined.
2. Security bits are independent of each other. Full-chip erase may be performed regardless of the states of the security bits.
3. Setting LB doesn’t prevent programming of unprogrammed bits.

Security
The security feature protects against software piracy and prevents the contents of the Flash from being read. The Security Lock bits are located
in Flash. The XA-G49 has 3 programmable security lock bits that will provide different levels of protection for the on-chip code and data (see
Table 3).
