AM3352 Ethernet Subsystem's loopback function

Guru 16800 points

Hello,

In the technical reference manual at 14.1.1, there are two loopback functions are described, digital loopback and FIFO loopback.
However, I can't find the concrete description for the digital loopback.
Could you teach me about the digital loopback; for example, where is the loopback point, what data is loop backed, and so on.

Best Regards.
