resistors to form a resistor
divider circuit.
NOTE: If the RGMII mode of the EMAC is not used, the DV

RSV13, and RSV14 pins can be connected to directly ground (V
SS
) to save
power. However, connecting these pins directly to ground will prevent
boundary-scan from functioning on the RGMII pins of the EMAC. To preserve
boundary-scan functionality on the RGMII pins, see
Section 7.3.4 .
