Reference Manual
Table 2–11 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 control DIP switch
■ PCI Express control DIP switch
■ MAX V reset push button
■ Program load push button
■ Program select push button
■ CPU reset push button
Board Settings DIP Switch
The board settings DIP switch (SW5) controls various features specific to the board
and the MAX V CPLD System Controller logic design.
Table 2–12 lists the switch
controls and descriptions.
D4, D5, D6 PGM_LED
PGM_LED0
PGM_LED1
PGM_LED2
The sequence displayed determines if the factory design or a
user design is used to configure the FPGA from flash when you
press the PGM_LOAD push button. Refer to
Table 2–9 for the
push button configuration settings.
D12 TEMP OVERTEMPn
Red LED. Illuminates when a heat sink or fan should be installed.
Driven by the MAX1619 thermal sensor OVERTEMPn signal.
