DP83630: LINK-LED changing polarity

M.A.M

Part Number: DP83630

Hi team,

My customer is investigating why LED-LINK function seems to change polarity, although I do not see such a config register functionality, so I need your assistance to reveal the root cause.

- Can we take it offline please?

Hello,

Perhaps it could be the I/O configuration of your LED_LINK. Have you referred to Section 10.2.5 of the LEDCR 'LED Direct Control Register'?

Thanks,

Cecilia

Cecilia,

Yes, we have looked at this register, but there it can just disable LED-LINK or set it to a fixed value. Customer claim polarity change so I believe that I need more in-depth support from you, including sending over sensitive info to you.

- Can I please have a contact to discuss further with directly?

Thanks.

Hello,

Before we do a direct contact, does your customer believe it is changing polarity after the fact that they are setting it as either the intended input or output?

Thanks,

Cecilia
