7 years agoHi, The Loop_ENA bit is used to enable the MAC Loopback, and it should work. You can refer to the TSE user guide, section Section 5.3, when you set the TX_ENA & RX_ENA, you can also set the Loop_ENA to 1.

As for the example design, you can refer to the AN647, there is a tcl script that allow the use to configure the internal MAC loopback (page 17).
