97 / 168 page  RGMII[x] RD 3 _ [ :0] (B) RGMII[x] RX_CTL _ (B) RGMII[x] RXC _ (A) RGMII4 RXERR RXDV 2nd Half-byte 1st Half-byte RGMII2 RGMII3 RGMII1 RGMII5 A. RGMII[x]_RXC must be externally delayed relative to the data and control pins. B. Data and control information is received using both edges of the clocks. RGMII[x]_RD[3:0] carries data bits 3-0 on the rising edge of RGMII[x]_RXC and data bits 7-4 on the falling edge of RGMII[x]_RXC. Similarly, RGMII[x]_RX_CTL carries RXDV on rising edge of RGMII[x]_RXC and RXERR on falling edge of RGMII[x]_RXC. Figure 6-9.
