Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Hello.
We are testing the use of TM4C1294NCPDT for our new design.

For Ethernet compliance testing,
does the TM4C1294 have some register to setting or regulating of wave?

Do you have any test program for 10Base-T on TM4C1294 for ethernet testing?
We found following regisers;

Ethernet PHY 10Base-T Status/Control - MR26 (EPHY10BTSC),

Is there any register to control 10Base-T, and/or 100Base-TX wave?

Regards,

Komagome

Hi,
Are you referring to the wave as in EMI? There is no registers to regulate the wave if this is what you are talking about.

Perhaps they desire a test pattern or how to configure the loop back register settings?

HI,
I have not heard back from you. Are you clear now that there is no registers for regulating the wave? I will close this thread for now. If you have new questions you can open a new thread or you can reopen this thread if you need further resistance.

Thank you for your response.

Can I ask you about that again?

We think that we need to adjust the waveform.

The simple environment we use is as follows;

EK-TM4C1294XL --- HUB --- PC

We want to know if we can or can not to;

- adjust amplitude of differential signal ?

- adjust pulse period ?

- generate test pattern ?

- other useful parameters ?

Thanks for your help.

Hi Koma,
Other than the Ethernet PHY Cable Diagnostic Control register (EPHYCDCR) I don't really find any registers that allow changing the amplitude or pulse width of the differential signal. I'm not sure if EPHYCDCR is of any interest to you.
