    • Switches to battery power only when the +3.3 V system power supply is off. G.1.3 Reset Generator The RCM5700/RCM6700 uses a reset generator to reset the Rabbit microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 2.85 V and 3.00 V, typically 2.93 V.
