Abstract:
The present invention is a method and apparatus for updating a timer from a plurality of timing domains. An arbitration circuit arbitrates the update requests from the plurality of timing domains. The plurality of timing domains include at least a counter. The update requests provide the update values. A multiplexer, which is coupled to receive the update values, selects a timer value from the update values. A timer register which is coupled to the multiplexer stores the timer value synchronously with a local clock signal.
