4.5 RGMII1/VIN2A Selection (Mux F)
Table 20 is part of the SoC pinmux table for VIN2A (upper data bits). 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 (RGMII1): TXC, TXCTL, TXD[3:0], RXC, RXCTL, RXD[3:0]
• Video Input Port (VIN2A): D[23:12]
