ABSTRACT:
An activity sensor monitors a microprocessor based system for a change in a logic state. In response to the change, the activity sensor provides a reset timer pulse to a delay timer circuit. The delay timer is a counter that stores a signal representation of the number of timing pulses provided by a timing clock. In response to the timer reset signal, the delay timer is reset. When the timer reset pulse is not provided for a predetermined interval, the delay timer generates a timeout pulse that causes a reduction in the frequency of a system clock.
