For low power standby applications, one is -far- better off using an
outboard LVD, rather than the power hungry BOD. (0.3uA vs 85uA)
Also, the BOD on the 16LF87* parts has a trip point of 4V (or so)
making it useless for 3.3V or 2V powered systems. AFAICT the
BOD is USELESS for battery powered systems.

Make it variable setpoint, and -much- lower power, and it might
become useful.
