Hi
There are a few issues find in the DP83867IS Ethernet Compliance Testing according to the procedure in the doc below:
1. The DP83867 peripheral hardware circuit address is configured as 0001, but what I read from the register is 1110;
2. After linking, I use an oscilloscope to test. After configuring the test mode register as written in the reference document, only the first group of the 4 groups of differential outputs has signals, and the other three groups of differential lines have no signal output;
3. Read the register configuration. Some configurations are either 00 or ff, which do not correspond to actual functions.
Please find the reading result in and schematic as below:
