Mux F: Selects between Gig Ethernet, expansion, and combines with Mux E to support LI camera. The
selection is made using the IO expander #3, and bits P12 and P11, with the default set to Gig Ethernet.
The MDIO mux setting (shown in
the MDIO function is provided by other pins. The mux selection for MDIO is automatic, based on the
RGMII0 mux setting.

Figure 17 is part of the SoC pinmux table for RGMII0. The SoC device supports additional functions not
shown in the table. The functions shown are intended to reflect those supported on the EVM. These
include:
• Gig Ethernet (RGMII0): TXC, TXCTL, TXD[3:0], RXC, RXCTL, RXD[3:0]
• Management Data I/O (MDIO): MCLK, D
• Video Input Port (VIN1B): CLK, HSYNC, VSYNC, DE, [7:0]
