3.8 Operation During Code ProtectWhen the data EEPROM is code protected, the micro- controller can read and write to the EEPROM normally. However, all external access to the EEPROM is dis- abled. External write access to the program memory is also disabled.
When program memory is code protected, the micro- controller can read and write to program memory nor- mally, as well as execute instructions. Writes by the device may be selectively inhibited to regions of the memory, depending on the setting of bits WR1:WR0 of the configuration word (see Section 14.1 for additional information). External access to the memory is also disabled =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
