Configuration, Status, and Setup Elements

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.
