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 P89C60X2/61X2 has 3 programmable security lock bits that will provide different levels of protection for the on-chip code
and data (see Table 3). Unlike the ROM and OTP versions, the security lock bits are independent. LB3 includes the security protection of LB1.
Table 3.
SECURITY LOCK BITS

PROTECTION DESCRIPTION
Level
LB1
MOVC instructions executed from external program memory are disabled from fetching code bytes from
internal memory.
LB2
Program verification is disabled
LB3
External execution is disabled.
NOTE:
1. The security lock bits are independent.
