Enabling Brown-out Reset does not automatically enable Power-up Timer.
The entire data EEPROM will be erased when the code protection is turned off.
The entire program memory will be erased when the code protection is turned off.
When MCLR is asserted in INTOSC or RC mode, the internal clock oscillator is disabled.
