Abstract
Herein described are at least a method and a system for prioritizing the transmission of one or more types of signals through a serial port. Various aspects of the present invention may be implemented using a serial port interface module that facilitates communication between any two devices. In a representative embodiment, the two devices comprise a disk drive controller and a disk drive motor controller used in a hard disk drive. In a representative embodiment, the method and the system are used in the hard disk drive for prioritizing the transmission of multirate voice coil motor (VCM) updates and other asynchronous data signals between the disk drive controller and disk drive motor controller through the serial port.
