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 during an erase.
The entire program memory will be erased when the code protection is turned off.
Unemplemented on PIC16LF190X devices. This bit reads as ‘1’.
For PIC16LF190X only.
