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 P89C660/662/664/668 has 3 programmable security lock bits that will provide different levels of protection for the on-chip code
and data (see Table 16).
Table 16.

PROTECTION DESCRIPTION
Level
LB1
LB2
LB3
1
0
0
0
MOVC instructions executed from external program memory are disabled from fetching
code bytes from internal memory.
2
1
0
0
Same as level 1, plus block erase is disabled. Erase or programming of the status byte or
boot vector is disabled.
3
1
1
0
Same as level 2, plus verify of code memory is disabled.
4
1
1
1
Same as level 3, plus external execution is disabled.
NOTE:
1. Security bits are independent of each other. Full-chip erase may be performed regardless of the state of the security bits.
2. Any other combination of lockbits is undefined.
3. Setting LBx doesn’t prevent programming of unprogrammed bits.
