1. A glitch filtering circuit, comprising:
a counting circuit configured to provide one or more counter output signals indicating whether an input signal has remained in a first signaling state or in a second signaling state for a preconfigured duration of time;
a flipflop clocked by a clock signal and configured to provide an output of the glitch filtering circuit;
a threshold detect circuit configured to generate a select signal based on the one or more counter output signals; and
a multiplexer configured to provide a multiplexed signal to an input of the flipflop, the multiplexed signal having a signaling state that is selected in accordance with the select signal.
