9. GMII Transmit and Receive Operations (Gigabit Mode)
txd and tx_en are driven synchronous to the gtx_clk during transmit operations. When the frame being trans-
mitted has an error, tx_er is asserted.
When receiving data, rxd and rx_en are sampled on the rising edge of rx_clk. An error in the frame is indicated
when rx_er is asserted.
