  0. A programmable gate array comprising:  a plurality of logic modules, each logic module having at least one output coupled to an isolation transistor, each isolation transistor in each of said plurality of logic modules having a gate;  a first charge pump having a charge-pump enable input, a pump-voltage output coupled to said gates of each isolation transistor in each of said plurality of logic modules, and a pump-voltage-output-grounding input; a switching transistor coupled between said pump-voltage output of said first charge pump and an input/output pad of the programmable gate array, said switching transistor
