Patent ID: 7586356

Claim:
A method comprising: (a) passing a first signal through a multiplexer, onto an input lead of a delay element, through the delay element, onto an output lead of the delay element and onto a data input lead of a latch, wherein an input digital value is present on the input lead of the delay element as the first signal is passed onto the input lead of the delay element, and wherein an output digital value is present on the output lead as the first signal is passed onto the output lead; (b) detecting a transition-free period in the first signal by comparing the input digital value to the output digital value; (c) latching the latch during the transition-free period based on the detecting in (b); and (d) switching the multiplexer such that the first signal is no longer present on the data input lead of the latch but so that a second signal is present on the data input lead of the latch.
