Abstract
An interface controller coupling the main body of an external electronic device to a host, and the electronic device using the interface controller and a control method for the external electronic controller are disclosed. The interface controller has a control unit and a non-volatile memory. The control unit is configured to transmit a termination-on signal to the host when link information retrieved from the main body has been written into the non-volatile memory. When the host issues a link information request in response to the termination-on signal, the control unit uses the link information stored in the non-volatile memory to respond to the link information request.
Claims16
An interface controller, coupling a main body of an external electronic device to a host, comprising:
- a non-volatile memory;
- and
- a control unit, configured to transmit a termination-on signal to the host when link information retrieved from the main body has been written into the non-volatile memory,
- wherein when the host issues a link information request in response to the termination-on signal, the control unit uses the link information stored in the non-volatile memory to respond to the link information request.
An external electronic device, comprising:
- a main body;
- and
- an interface controller, coupling the main body to a host and comprising a control unit and a non-volatile memory,
- wherein:
- the control unit is configured to transmit a termination-on signal to the host when link information retrieved from the main body has been written into the non-volatile memory;
- and
- when the host issues a link information request in response to the termination-on signal, the control unit uses the link information stored in the non-volatile memory to respond to the link information request.
A control method for an external electronic device, comprising:
- providing an interface controller to couple a main body of the external electronic device to a host;
- retrieving link information from the main body and writing the link information into a non-volatile memory;
- transmitting a termination-on signal to the host after writing the link information into the non-volatile memory;
- and
- using the link information stored in the non-volatile memory to respond to a link information request that is issued by the host in response to the termination-on signal.
