Similar to the FPGA, the HPS also has its set of switches, buttons, LEDs, and other interfaces
connected exclusively. Users can control these interfaces to monitor the status of HPS.
Table 3-22
gives the pin assignment of all the LEDs, switches, and push-buttons.

The board supports Gigabit Ethernet transfer by an external Micrel KSZ9021RN PHY chip and
HPS Ethernet MAC function. The KSZ9021RN chip with integrated 10/100/1000 Mbps Gigabit
Ethernet transceiver also supports RGMII MAC interface.
Figure 3-31
shows the connections
between the HPS, Gigabit Ethernet PHY, and RJ-45 connector.
The pin assignment associated to Gigabit Ethernet interface is listed in
Table 3-23
. More
information about the KSZ9021RN PHY chip and its datasheet, as well as the application notes,
which are available on the manufacturer’s website.
