Gigabit Ethernet MAC

The AM335x provides a 10/100/1000 Mbit MAC Core.
Two Ethernet interfaces are routed to the TQMa335xL pads using the 3-port switch. The switch supports two MII, RMII and RGMII.
The following table shows the signals used.

GPMC / External memory bus

The AM335x provides a General Purpose Memory Controller (GPMC), whose pins are routed to the TQMa335xL pads.
The GPMC signals are routed to the TQMa335xL pads as secondary function. GPMC-CLK is multiplexed with MMC1-CLK.

Note: Signal overlapping

There is an overlapping with an eMMC signal.
GPMC-CLK is multiplexed with MMC1-CLK.

1: Currently not supported.
