Abstract
A method is provided, for example, to implement multiplexed communication between a controller and a preamplifier in a storage device. For example, multiplexed communication is implemented by controlling a bidirectional serial data line of a digital bus to selectively transmit digital signals in either a first direction from the controller to the preamplifier or a second direction from the preamplifier to the controller, in response to a direction control signal, and concurrently transmitting a synchronous clock signal over a clock signal line of the digital bus from the controller to the preamplifier to synchronize transfer and processing of the digital signals transmitted on the bidirectional serial data line of the digital bus. The direction control signal is transmitted from the controller to the preamplifier on one of the bidirectional serial data line and the clock signal line of the digital bus.
