Abstract
A system and method for providing an interface between a read channel and a disk controller. The interface includes a plurality of differential pair signal lines operable o communicate data and control signals between the read channel and the hard disk controller. The data and control signal lines communicate operations for transferring data between the disk controller and the read channel. The operations may be communicated as commands that may be communicated to a preamplifier circuit to access registers in the preamplifier that may be configured to control the preamplifier operation.
