Table 2–14 lists the JTAG control DIP switch component references and
manufacturing information.
PCI Express Control DIP switch
The PCI Express control DIP switch is provided to enable or disable the different
configurations.
Table 2–15 shows the switch controls and descriptions.
Table 2–16 lists the PCI Express control DIP switch component reference and
manufacturing information.
Reset Configuration Push-Button Switch
The reset configuration push-button switch, RESET_CONFIGn, 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
input from the rotary switch position when the button is released. Valid locations
include 0 and 1 for the two pages in flash reserved for FPGA designs.
