Enabling Brown-out Reset does not automatically enable Power-up Timer.
Program memory bulk erase must be performed to turn off code protection.
The entire data EEPROM 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.
If the HS, XT, or LP oscillator fails In Fail-safe mode the Watchdog time-out can occur only once after
which it will be disabled until the oscillator is restored.
