CCS/TLK105: CCS/TLK105

Tool/software: Code Composer Studio

Hello,

I want to use the RMII mode for the TLK105 Phy but in the "RMII Control and Status Register" with Adr. 0x0017 I can't set the Bit 5 for the RMII Mode.

Doesn't this device support this mode? To set Bit for is working, so there is no access problem.

    Hi Jaikey,

    The TLK105 does support RMII but you should set this mode using the strap pin rather than through register access.

    The different frequency requirements between RMII and MII makes it difficult to bring up the part then change reference and restart the device by software.

    Best Regards,
