EMAC[1] RMII 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, 01b is RMII 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 RMII mode is selected.
