DP83TG720R-Q1: DP83TC812

Hi Hongsheng,

Happy to help. Is there any area I can assist with?

Best,

Nick

Hello, Nick,

    We use DP83TC812 in out project and I am responsible for MDI compliance testing. my question is 

   1) If I want to set DG83TC812 to test mode for MDI test, what kind of tool can be used? I have a tool named TI LaunchPad kit with MSP430MCU which I used to config DP83TG720 registers. Can I use this tool for C812?

   2) Is there any document of how to set test mode and register information of DG83TC812?

I am very appreciated for your supporting!

regards,

Huan Hongsehng

Hi Huan Hongsheng,

I would recommend that you review the Open Alliance Appnote on the DP83TC81X devices:

https://www.ti.com/lit/an/snla389e/snla389e.pdf

To configure devices, we still use the MSP430MCU. You can use the tool USB2MDIO to access register settings:

Hi，Nick,

   thanks for your support. I will try to use USB2MDIO tool to config the chip once PCB is ready
