DP83822H: Communication error when cable connect/disconnect test

Part Number: DP83822H

Hello,

We are testing cable plug/unplug test and error occurs around once in 5 to 10 times. 1:1 connection and both phys are DP83822.

When this error occurs, Bit9 of 0x0010 PHY Status Register (PHYSTS) becomes 0. bit0 Link Status is 1 so we think link is established.

This error is gone if power cycle does.

What is occurring this and would you advice us how to solve this issue?

Best regards,

Toshihiro Watanabe
