Abstract
A method for adjusting a drive control signal for a motor includes providing a drive circuit having a first pin and a second pin, wherein the drive circuit generates the drive signal. 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. One of the advance angle count value and a first control signal coupled to the first input pin are used to determine an advance angle adjustment range or an advance angle count range and a second control signal received via the second input pin are used to determine an advance angle adjustment range. The drive control signal is adjusted in response to the advance angle adjustment range.
