5.1.9.2. Interface to HPS IO Pins

HPS RGMII interface is connected to HPS dedicated I/O pins through the platform designer HPS pinmux configuration. Similarly, MDIO interface and timestamp interface are instantiated together with EMAC selection in pinmux configuration.

The MDIO interface consist of MDC and MDIO signals routed to HPS dedicated I/O to serve as PHY management interface for external RGMII PHY.

The timestamp interface PPSTRIG and PPS signals serve respectively as 1PPS input and output signal through HPS dedicated I/O in this case.
