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.
