The TEMAC solution always provides support for full-duplex Ethernet. However, to provide half-duplex operation, further FPGA logic resources are required. Because many applications require only full-duplex support, the half-duplex logic is therefore optional. When the core is generated with half-duplex logic, full- or half-duplex operation can be selected using TEMAC configuration. The default is not to include half-duplex support. When the data rate is set to 2.5 Gbps or if half-duplex is selected the AVB option is disabled.

Note: If an MMCM is used on the physical interface receive path to control the clock-to-data relationship, 1 Gbps half-duplex is not supported.

The Features tab is shown in previous figure and includes the following options:
