RXPHASE_SEL This bit is used to adjust RX clock phase at
GMII/ RGMII interface
0: No intentional delay is added on RX_CLK
1: An intentional delay is added on RX_CLK
(about 2ns delay in 1000BASE-T, and about
4ns delay in 100BASE-TX and 10BASE-T).
(Pin 48 sets the default value of this bit)

TXPHASE_SEL
This bit is used to adjust TX clock phase at
GMII/ RGMII interface
0: No intentional delay is added on
GTX_CLK/ TXC
1: An intentional delay is added on
GTX_CLK/ TXC
(about 2ns delay in 1000BASE-T, and about
4ns delay in 100BASE-TX and 10BASE-T)
Pin 49 sets the default value of this bit.
