In accordance with an embodiment, a method for driving a motor includes generating a position indicator signal in response to a signal from the at least one Hall sensor, wherein the position indicator signal has a first period. A phase shift value is generated using the position indicator signal. The position indicator signal is used to generate an adjusted position indicator signal in response to the phase shift value. In accordance with another embodiment, a lead angle adjustment circuit includes a counter coupled to a subtractor circuit through a multiplier circuit. A storage register is coupled to the output of the counter and to an input of a slope determination circuit, wherein the slope determination circuit is coupled to a first external pin of the lead angle adjustment circuit. A multiplier circuit is coupled to the slope determination circuit and to a second external pin.
