There is disclosed a system for detecting the assertion of a reset signal. A plurality of circuit elements is configurable by a reset signal to output a string of data values in a predetermined pattern. A comparator receives the string of data values and determines whether the string of data values matches the predetermined pattern. If so, the comparator generates an output signal indicative of a reset. In one embodiment, the output signal of the comparator can be used to automatically trigger a reset if the reset signal has not been asserted.
