A common situation is interfacing an electromechanical load with a microprocessor. One problem with interfacing an electromechanical load with a microprocessor is that the drive requirements of the electromechanical load is usually outside the capability of the microprocessor device. To meet these drive requirements, it is conventional to add a circuit board between the electromechanical load and the microprocessor device. An alternative solution is to incorporate a higher capability driver into the load or to include the higher capability driver within the confines of the microprocessor. Although these solutions will enable the connection of an electromechanical load requiring a higher drive current and a microprocessor device, these solutions reduce the interconnectability between electromechanical loads and microprocessor units. More specifically, if the higher capability driver is incorporated in the microprocessor unit, one output slot of the microprocessor unit would then be dedicated to connections to electromechanical loads, thus reducing the configurability of the microprocessor.
