MAX II CPLD.
D36 Factory
Illuminates when FPGA is configured with the default factory FPGA design. Driven by
the MAX II CPLD.
D35 User
Illuminates when FPGA is configured with a design other than the default factory FPGA
design. Driven by the MAX II CPLD.
D14 ENET TX
Illuminates when transmit data is active from the Ethernet PHY. Driven by the Marvell
88E1111 PHY.
D15 ENET RX
