16.2.4
The BOREN0 and BOREN1 bits in the Configuration
Word register selects 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 of the PCON register enables/disables
the BOR allowing it to be controlled in software. By
selecting BOREN<1:0>, the BOR is automatically dis-
abled in Sleep to conserve power and enabled on
wake-up. In this mode, the SBOREN bit is disabled.
See Register 16-1 for the Configuration Word defini-
tion.

The PIC16F91X/946 stores the BOR calibration values
in fuses located in the Calibration Word (2008h). The
Calibration Word is not erased when using the
specified bulk erase sequence in the “PIC16F91X/946
Memory Programming Specification” (DS41244) and
thus, does not require reprogramming.

space (2000h-3FFFh), which can be accessed only
during programming. See “PIC16F91X/946 Memory
