PIC12F683
12.3.4
The BODEN0 and BODEN1 bits in the Configuration
Word register select one of four BOD modes. Two
modes have been added to allow software or hardware
control of the BOD enable. When BODEN<1:0> = 01,
the SBODEN bit (PCON<4>) enables/disables the
BOD allowing it to be controlled in software. By select-
ing BODEN<1:0>, the BOD is automatically disabled in
Sleep to conserve power and enabled on wake-up. In
this mode, the SBODEN bit is disabled. See
Register 12-1 for the Configuration Word
definition.

12.3.4.1
The PIC12F683 stores the BOD calibration values in
fuses located in the Calibration Word register (2008h).
The Calibration Word register is not erased when using
the specified bulk erase sequence in the “PIC12F6XX/
16F6XX
(DS41204) and thus, does not require reprogramming.
