6.12.3 Auxiliary Supply System

The auxiliary supply system can operate the device from auxiliary supplies when the primary supply fails. There are two auxiliary supplies supported: AUXVCC1 and AUXVCC2. This module supports automatic and manual switching from primary supply to auxiliary supplies while maintaining full functionality. It allows threshold based monitoring of primary and auxiliary supplies. The device can be started from primary supply or AUXVCC1, whichever is higher. The auxiliary supply system enables internal monitoring of voltage levels on primary and auxiliary supplies using ADC10_A. Also this module implements simple charger for backup supplies.
