Abstract: A shared pair of input/output cells configured to be able to be connected to a first external resonator or a second external resonator. A first oscillator and a second oscillator are coupled to the shared pair input/output cells by a switching circuit. The switching circuit is configured to be able to connect either the first oscillator or the second oscillator to the pair of input/output cells.
