Abstract
In an embodiment a processing system includes a sub-circuit including a three-state driver circuit, wherein the three-state driver circuit has a combinational logic circuit configured to monitor logic levels of a first signal and a second signal, and selectively activate one of the following switching states as a function of the logic levels of the first signal and the second signal: in a first switching state, connect the transmission terminal to the positive supply terminal by closing the first electronic switch, in a second switching state, connect the transmission terminal to the negative supply terminal by closing the second electronic switch, and in a third switching state, put the transmission terminal in a high-impedance state by opening the first electronic switch and the second electronic switch.
