The described embodiments provide a circuit that can be configured as a pulse generator or as an oscillator. The circuit includes a pulse generator circuit and a test circuit that is coupled to the pulse generator circuit. In the described embodiments, an disable signal is coupled to the test circuit. When the disable signal is asserted, the test circuit is disabled, and the pulse generator circuit outputs pulses of a predetermined duration. In contrast, when the disable signal is deasserted, the test circuit is enabled, and the pulse generator circuit outputs an oscillating signal.
