1. A device, comprising:
- operational logic responsive to communication signals over an interface for performing input/output operations, the operational logic providing a first and a second mode of operation, the second mode of operation consuming less power than the first mode of operation; and
power control logic including a memory, the power control logic controlling the operational logic when the operational logic is in the second mode of operation, the power control logic being coupled to the communication signals over the interface and configuring the memory for storing data when a predetermined communication signal is received by the power control logic, the data being related to the predetermined signal.

Abstract
Power control logic in a disk drive controls a mode of operation of operational logic of the disk drive for reduced power consumption. The operational logic includes a first and a second mode of operation, such that the second mode of operation consumes less power than the first mode of operation. The power control logic includes a memory, and is coupled to communication signals over an interface. In response to a predetermined communication signal, the power control logic configures the memory for storing data that is related to the predetermined communication signal.

23. A method for controlling power of a device, the device having operational logic, the method comprising steps of:
-
detecting a communication signal over an interface intended for the operational logic of the device, the operational logic having a first mode of operation and a second mode of operation, the operational logic consuming more power in the first mode of operation than in the second mode of operation, the communication signal being detected when the operational logic is in the second mode of operation; and
configuring a memory for storing data when a predetermined communication signal is received by the power control logic, the data being related to the predetermined signal. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
