ABSTRACT:
In one embodiment, a motor drive is provided that includes a control board and one or more option boards coupled to the control board via one or more serial interfaces such that data from the one or more option boards is communicated via one or more synchronous interrupts on the one or more serial interfaces. A method of operating a motor drive that includes transmitting one or more signals from an option board to a control board via one or more synchronous interrupts, wherein the option board is coupled to the control board via a serial interface. A tangible machine-readable medium implementing the method is also provided.
