CONFIG – CONFIGURATION WORD REGISTER
Enabling Brown-out Reset does not automatically enable the Power-up Timer (PWRT) the way it does on the
PIC16F627/628 devices.
The code protection scheme has changed from the code protection scheme used on the PIC16F627/628 devices. The
entire Flash program memory needs to be bulk erased to set the CP bit, turning the code protection off. See
“PIC16F627A/628A/648A EEPROM Memory 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 “PIC16F627A/
628A/648A EEPROM Memory Programming Specification” (DS41196) for details.
When MCLR is asserted in INTOSC mode, the internal clock oscillator is disabled.
