Abstract

In a battery powered data processing system having an oscillator and a microprocessor connected to the oscillator, the microprocessor has a programmable standby mode and circuit responsive to the standby mode for disabling the oscillator. The system uses a sensor circuit to generate a reset signal to reset the microprocessor from the power down mode when a key is depressed. A signal generator is responsive to signals from the oscillator for disabling the reset signal.
