Programmable Logic Jtag Programming Options - Xilinx ZCU111 User Manual

The LED functions can be repurposed with a LEDCR1 register write available via the PHY's
management data interface, MDIO/MDC. LED_2 is assigned to ACT (activity indicator) and
LED_0 indicates link established. For more Ethernet PHY details, see the TI DP83867 data
sheet [Ref 20]. LED_1 (100BASE-T link established) is a separate LED DS27 located on the
top side of the board near the RJ45 P12 connector
