button (S3).
FPGA Programming over External USB-Blaster
The JTAG programming header provides another method for configuring the FPGA
using an external USB-Blaster device with the Quartus II Programmer running on a
PC. The external USB-Blaster connects to the board through the JTAG connector (J5).
Both FPGAs and the MAX II devices are always in the JTAG chain.

Description
D1 Power — 5.0-V Blue LED. Illuminates when 5.0 V power is active.
D16 MAX_CONF_DONE1 — 2.5-V
Green LED. Illuminates when the MAX II CPLD
EPM2210 System Controller is successfully
configured. Driven by the MAX II CPLD EPM2210
System Controller.
D17 MAX_LOAD1 — 2.5-V
Green LED. Illuminates when the MAX II CPLD
EPM2210 System Controller is actively configuring
the FPGA. Driven by the MAX II CPLD EPM2210
System Controller wire-OR'd with the on-board
USB-Blaster II CPLD.
D15 MAX_ERROR1 — 2.5-V
Red LED. Illuminates when the MAX II CPLD
EPM2210 System Controller fails to configure the
FPGA. Driven by the MAX II CPLD EPM2210
System Controller.
D12, D13,
D14
PGM1_LED[2:0] — 2.5-V
Green LEDs. Illuminates to indicate which hardware
page loads from flash memory when you press the
PGM1_SEL
push button or when you power-on the
board.
