PMC MIO[48] and LPD_MIO[0:11, 24:25]: GEM0 Ethernet
[Figure 1, callout 19]
A PS Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mbps Ethernet
interface. In the following figure, the device (U1) is connected to ADI ADIN1300
U198 Ethernet RGMII PHY before being routed to an RJ45 Ethernet connector J307.
The RGMII Ethernet PHY is boot strapped to PHY address (0x01) and Auto
Negotiation is set to Enable.

Ethernet PHY (Three Resets)
[Figure 1, callout 19]
The ADIN1300 PHY (GEM0 U198) is reset by its GEM0_RESET_B generated by
dedicated pushbutton switch (SW15) and PMC_MIO signals as shown in the
following figure. The POR_B signal generated by the TPS389001DSER U10 POR
device is wired in parallel to each Ethernet PHY reset circuit. The POR device is
activated by pushbutton SW2. See
