DP83849I:MII通信のMDIOとMDCについて

Part Number: DP83849I

DP83849IVSのICについてご質問があります。

現在、DP83849IVSとルネサス系CPU(RX71M)を使用してLAN通信を2ch分、実現しようと考えています。

そこでMII通信のMDIOとMDCについてルネサス系CPU(RX71M)は2ch分ありますが
DP83849IVSには1ch分(共通)しかありません。
LAN通信を2ch分、実現しようとした場合どのような接続になるのでしょうか。
ご教授お願いいたします。

    Hello,

    Using a single channel of MDC/MDIO should allow for multiple PHYs to be programmed, as the channel is a multi-port bus system.

    PHYs with different addresses can be connected and controlled by a single bus.

    We are not aware of this CPU, please check with Reneas for more information on RX71M functionality and configuration.

    Thank you,

    Evan
