Abstract
A transceiver module is provided with a transceiver IC (PHY IC) having an XENPAK register group including an status register, and a DCU having an XENPAK register group which emulates the XENPAK register group. The PHY IC has an operation mode in which it does not reply to access to the XENPAK register group by a host while the DCU emulates the structure and function of the XENPAK register group.
Claims3
A transceiver module comprising:
- a physical-layer integrated circuit having a physical-layer register unit including an error flag register to which a bit value indicating occurrence of an error is set;
- and
- a control integrated circuit having a control-side register unit which emulates structure and function of said physical-layer register unit, said physical-layer integrated circuit having an operation mode in which it does not reply to access to said physical-layer register unit by a higher-layer device while said control integrated circuit emulates the structure and function of said physical-layer register unit.
