15.3.4
The BOREN0 and BOREN1 bits in the Configuration
Word select one of four BOR modes. Two modes have
been added to allow software or hardware control of
the BOR enable. When BOREN<1:0> = 01, the
SBOREN bit (PCON<4>) enables/disables the BOR
allowing it to be controlled in software. By selecting
BOREN<1:0>, the BOR is automatically disabled in
Sleep to conserve power and enabled on wake-up. In
this mode, the SBOREN bit is disabled. See
Register 15-1 for the Configuration Word definition.

The PIC16F785 stores the BOR calibration values in
fuses located in the Calibration Word (2008h). The
Calibration Word is not erased when using the speci-
fied bulk erase sequence in the PIC16F785 Memory
Programming Specification (DS41237) and thus, does
not require reprogramming.
