Abstract
A monitor circuit (301) for monitoring changes in an input digital value of a register circuit comprises a data input (302) configured to receive a copy of the input digital value of said register circuit, and one or more triggering signal inputs (303) configured to receive one or more triggering signals. One or more triggering edges thereof define an allowable time limit before which a digital value must appear at a data input of said register circuit to become properly stored in said register circuit. The monitor circuit comprises a data event (DE) output (305), so that said monitor circuit is configured to produce a DE signal at said DE output (305) in response to a digital value at said data input (302) changing within a time window defined by said one or more triggering signals.
