Table 2–15 lists the JTAG chain header switch component reference and
manufacturing information.
PCI Express Control DIP Switch
The PCI Express control DIP switch (SW3) is provided to enable or disable different
configurations.
Table 2–16 shows the switch controls and descriptions.
Table 2–17 lists the PCI Express control DIP switch component reference and
manufacturing information.
Reset Configuration Push-button Switches
The load image push-button switch, RESET_CONFIGn (LOAD IMAGE) (PB5), is an
input to the MAX
II CPLD EPM2210 System Controller. The push-button switch forces
a reconfiguration of the FPGA from flash memory. The location in the flash memory is
based on the LED_CONFIG_LED[2:0] setting when the button is released. Valid
settings include LED_CONFIG_LED0, LED_CONFIG_LED1, or LED_CONFIG_LED2 on
the three pages in flash memory reserved for FPGA designs.
The image select push-button switch, factory (IMAGE SEL)(PB6), toggles the
LED_CONFIG_LED[2:0]
sequence. Refer to Table 2–9 for the
LED_CONFIG_LED[2:0] sequence definitions.
The MAX II reset push-button switch, MAX_RESETn (PB4), resets the MAX II CPLD
EPM2210 System Controller.
