Part 7 Security Features
The 56F8014 offers security features intended to prevent unauthorized users from reading the contents of
the flash memory (FM) array. The 56F8014’s flash security consists of several hardware interlocks that
prevent unauthorized users from gaining access to the flash array.
After flash security is set, an authorized user is still able to access on-chip memory if the user purposely
includes a subroutine to read and transfer the contents of internal memory via serial communication
peripherals, as this code would defeat the purpose of security.
7.1 Operation with Security Enabled
After the user has programmed the flash with his application code, the 56F8014 can be secured by
programming a security word ($E70A) into program memory location $00 1FF7. This nonvolatile word
will keep the device secured through reset and through power-down of the device. Refer to the flash
