PIC12F683
12.3.5
The BODEN0 and BODEN1 bits in the configuration
word selects 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 selecting
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.
