Patent ID: 7711997

Claim:
A method of controlling a transceiver module which includes a physical-layer integrated circuit having a physical-layer register unit, and a control integrated circuit having a control-side register unit, the method comprising: emulating the physical-layer register unit with the control-side register unit; prohibiting generation of a first error signal by the physical-layer integrated circuit, the first error signal giving notice of detection of a specific error directly to a higher-layer device; outputting a second error signal from the physical-layer integrated circuit, the second error signal giving notice of a high-speed error associated with communication processing and detected by the physical-layer integrated circuit, to the control integrated circuit; and specifying, by the control integrated circuit, the high-speed error in response to the outputting of the second error signal; setting a bit in the control-side register unit in response to the specifying of a high speed error by the control integrated circuit; and delivering, by the control integrated circuit, to the higher-layer device, as the first error signal, the second error signal specifying detection of a high-speed error.
