Abstract:
1. In a first digital component, for use with a host device, said host device being configured for issuing a set of commands on an interface such that a group of said commands can be directed to the first digital component on said interface for use in executing an operational mode thereof and other ones of said commands can be directed to one or more different components that can be connected to said interface along with said first digital component, and which interface is characterized by an idle time between said commands, an apparatus comprising: a control arrangement that draws an input current for operation thereof and is configured for monitoring said interface for any one of said group of commands and, upon detecting an issued one of the group of commands on said interface, operates the first digital component for executing the issued command in the operational mode, and during said idle time, said control arrangement exclusively monitors said interface for any one of said group of commands such that said input current is limited to a leakage current; wherein said control arrangement includes a first section for monitoring said interface during said idle time and which draws said leakage current during the idle time and a second section that is configured to cooperate with the first section during said operational mode to execute said issued command and which second section is powered down by the first section when said first section draws said leakage current such that the second section is unpowered during the idle time.
