14.6
Data memory can be code-protected by programming
the CPD bit in the Configuration Word (Register 15.2)
to ‘0’.
When the data memory is code-protected, the CPU is
able to read and write data to the data EEPROM. It is
recommended that the user code protect the program
memory when code protecting the data memory. This
prevents anyone from programming zeroes over the
existing code (which will execute as NOPs) to reach an
added routine, programmed in unused program mem-
ory, which outputs the contents of data memory.
Programming unused locations in program memory to
‘0’ will also help prevent data memory code protection
from becoming breached.
