Abstract
The proper operation of a phase locked loop is determined by monitoring certain signals within the loop for their phase relationship or duty cycle. If a malfunction of the loop is detected, proper operation may be imposed or restored by resetting a phase-frequency detector, or by flipping the output of the phase-frequency detector.
