Enabling Brown-out Reset does not automatically enable Power-up Timer.
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.
MPLAB^® IDE masks unimplemented Configuration bits to ‘0’.

Note 1:
Unimplemented: Read as ‘1’
VCAPEN<1:0>: Voltage Regulator Capacitor Enable bits
For the PIC16LF722A/723A:
These bits are ignored. All VCAP pin functions are disabled.
For the PIC16F722A/723A:
00 = VCAP functionality is enabled on RA0
01 = VCAP functionality is enabled on RA5
10 = VCAP functionality is enabled on RA6
11 = All VCAP functions are disabled (not recommended)
Unimplemented: Read as ‘1’
MPLAB^® IDE masks unimplemented Configuration bits to ‘0’.
