Abstract
An MDIO interface transmits and receives data to and from a host device through an upper serial bus. An MDIO interface transmits and receives data to and from a client device through a lower serial bus. A CPU controls the MDIO interface and the MDIO interface, and controls data transfer between the host device and the client device. It is, therefore, possible that the CPU controls the client device connected to the lower serial bus.
Claims6
A microcomputer system employed in a network for transmitting data corresponding to a request from a host device within predetermined time in response to said request, comprising:
- a first interface transmitting and receiving data to and from said host device through an upper bus;
- a second interface transmitting and receiving data to and from a client device through a lower bus physically different from said upper bus;
- and
- a processor controlling said first interface and said second interface, and controlling data transfer between said host device and said client device.
