Chapter 2: Board Components 2–17

Configuration, Status, and Setup Elements

Table 2–10 lists the board-specific LEDs component references and manufacturing

information.

Setup Elements

The development board includes several different kinds of setup elements. This

section describes the following setup elements:

■ Board settings DIP switch

■ JTAG chain header switch

■ Configuration push-button switches

Board Settings DIP Switch

The board settings DIP switch (SW2) controls various features specific to the board

and the MAX

II CPLD EPM2210 System Controller logic design. Table 2–11 shows the

switch controls and descriptions.

D29, D30, D31 PROGRAM

(PGM_LED[2:0])

Green LEDs. Illuminates to show the LED sequence that determines which flash

memory image loads to the FPGA when PGM select push-button switch is

pressed. Driven by the MAX II CPLD EPM2210 System Controller.

D22 ENET TX Green LED. Illuminates to indicate Ethernet PHY transmit activity. Driven by the

Marvell 88E1111 PHY.

D18 ENET RX Green LED. Illuminates to indicate Ethernet PHY receive activity. Driven by the

Marvell 88E1111 PHY.

D20 10 Green LED. Illuminates to indicate Ethernet linked at 10 Mbps connection speed.

Driven by the Marvell 88E1111 PHY.

D16 100 Green LED. Illuminates to indicate Ethernet linked at 100 Mbps connection speed.

Driven by the Marvell 88E1111 PHY.

D15 1000 Green LED. Illuminates to indicate Ethernet linked at 1000 Mbps connection

speed. Driven by the Marvell 88E1111 PHY.

D2 HSMA PRSNTn Green LED. Illuminates when HSMC port A has a board or cable plugged-in such

that pin 160 becomes grounded. Driven by the add-in card.

D1 HSMB PRSNTn Green LED. Illuminates when HSMC port B has a board or cable plugged-in such

that pin 160 becomes grounded. Driven by the add-in card.

D4 USB Green LED. Illuminates when the embedded USB-Blaster is in use to program the

FPGA. Driven by the MAX II CPLD EPM2210 System Controller and MAX IIZ.
