Abstract
A state machine is configured with a phase-locked loop clock signal generator which can operate at a rate faster than an externally generated reference clock signal applied to the phase-locked loop. The output of the phase-locked loop is used to trigger registers coupled to the state machine at a selected rate to enable signals at output terminals of the state machine to be updated at a rate different than the rate of the externally generated reference clock signal.
