Enabling Brown-out Reset does not automatically enable the Power-up Timer (PWRT) the way it did in the PIC16F627/628.
The code protection scheme has changed from the code protection scheme used in the PIC16F627/628. The entire Flash program mem-
ory needs to be bulk erased to set the CP bit, turning the code protection off. See Programming Specification DS41196 for details.
The entire data EEPROM needs to be bulk erased to set the CPD bit, turning the code protection off. See Programming Specification
DS41196 for details.
When MCLR is asserted in INTOSC mode, the internal clock oscillator is disabled.
