Abstract:
1. An interface circuit for performing communication with an upstream device and with a system controller for controlling a disc drive apparatus, the interface circuit comprising: an interface communication section for performing communication with the upstream device; a system interface communication section for performing communication with the system controller; and an interface control section for controlling the interface communication section and the system interface communication section; wherein the interface control section includes: (a) a first execution section for executing first reset processing; (b) a first request section for requesting the system interface communication section to request the system controller to permit execution of second reset processing which is different from the first reset processing; (c) a second request section for requesting the system interface communication section to receive a report of the permission of the execution of the second reset processing from the system controller; (d) a second execution section for executing the second reset processing in accordance with the report of the permission of the execution of the second reset processing; and (e) a third request section for requesting the interface communication section to report completion of the second reset processing to the upstream device.
