EMAC[0] RGMII Mode
An EMAC bootmode must be selected via the BTMODE[4:0] pins. Once the EMAC bootmode is selected, the BTMODE[9:8] pins determine
the Ethernet PHY Mode Selection (for example, 10b is RGMII mode). For more detailed information on EMAC bootmodes and Ethernet
PHY Mode selection, see Section 4.2.6, Ethernet PHY Mode Selection
These pin functions are available only when RGMII mode is selected.
