Abstract
A method for adjusting a drive signal of a drive circuit. A period of the drive signal is determined and an advance angle count value is extracted from a storage register in accordance with the period of the drive signal. The advance angle count value and a first control signal are used to determine an advance angle adjustment range, where the first control signal is from a source external to the drive circuit. The advance angle adjustment range and a second control signal are used to determine an advance angle adjustment range start angle, where the second control signal is from a source external to the drive circuit.
