I used the BOR in a PIC10LF320 together with the CLC.

This was to monitor voltage from a PV cell and do a long delay when input=20
voltage was above BOR voltage before power was let through to the actual=20
circuit. During this time only a rechargable battery was being charged so t=
here=20
would be enough charge to reliably start and run the rest of the circuit.=20
Without this long delay the circuit would start working directly but there =
was=20
not enough charge in the batteries and the current from the PV cells wasn't=
=20
enough so it just kept oscillating.

The long time (5 minutes I think, but could be programmed to as long as I w=
ant)=20
was done with sleep and WDT. After that, the PIC went to sleep and only the=
 CLC=20
part was operating. The CLC was then a simple OR circuit with two inputs us=
ed=20
to shut down the circuit from two different sources.
