Abstract
A glitch filter associated with a serial interface bus may receive an input signal associated with a glitch. The glitch filter may reject the glitch based at least in part on a plurality of state machine transitions associated with the glitch filter and a set of timers associated with the glitch filter, to produce an output signal that is not associated with the glitch. The glitch filter may provide the output signal. In some aspects, the set of timers includes a high timer and a low timer, and the input signal is locked at a high state for at least a length of the high timer and locked at a low state for at least a length of the low timer, in accordance with the plurality of state machine transitions. The glitch filter may be implemented as an asynchronous finite state machine (AFSM) filter or a synchronous finite state machine.
