hello, in the section "3.14 EMAC Loopback mode" of the document "80-pj388-23_f_emac_user_guide_for_third-party_phy_switch_integration_application_note.pdf" , we found three type loopback: MAC Loopback, Input output macro (IOMACRO) Loopback and PHY Loopback;
In the case "Mac Loopback mode", the SENDER send the data send to DUT(device Under Test), what will happen?
1. after data arrive to Mac of DUT, nothing will happen on the data, and won't be sent;
2. after data arrive to Mac of DUT, direct sent to SENDER;
Or, above is not correct, there will other happen
Thank you very much
