Abstract
A microcontroller is operable to monitor power supply levels corresponding, respectively, to a first power supply (e.g., a main power supply) and a second power supply (e.g., a battery backup power supply). In one or more modes of operation, the same brownout detector in the microcontroller alternately monitors signals corresponding, respectively, to the first and second power supply levels.
