Part Number: DP83TD510E

Hello,

 

Could you tell me how to access extended MMD resisters by clause 22 format on DP83TD510E?

 

Regards,

    To access MMDXX registers :

    write procedure :

    write reg<000D> = 0x00XX
    write reg<000E> = <address>
    write reg<000D> = 0x40XX
    write reg<000E> = <value>

    read procedure :

    write reg<000D> = 0x00XX
    write reg<000E> = <address>
    write reg<000D> = 0x40XX
    read reg<000E>

    Note : Above write and read procedure is normally used for registers with address greater than 0x001F. But it can also be used for any address in general.

    Hello,

    Thanks for your reply.

    Does it mean it is exactly the same way as DP83867 and DP83822?

    There is no description about REGCR and ADDAR resisters in DP83TD510E datasheet.
    So please add these information on the next datasheet update timing.

    Regards,
    Oba

    Yes it is same between 867 and 822. We noted your request for datasheet entry.
