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 89C51RB2/RC2/RD2 has 3 programmable
security lock bits that will provide different levels of protection for the
on-chip code and data (see Table 10).
