Detailed Description

FPGA_PROG_B Pushbutton SW3 (Active-Low)

The SW3 switch (Figure 1-21) grounds the FPGA PROG_B pin when pressed. This action clears the FPGA. See the Spartan-6 FPGA data sheet for more information on clearing the contents of the FPGA.

SYSACE_RESET_B Pushbutton SW9 (Active-Low)

When the System ACE CF configuration mode pin is high (enabled by closing DIP switch S1 switch 4), the System ACE CF controller configures the FPGA from the CompactFlash card when a card is inserted or the SYSACE RESET button is pressed. See “5. System ACE CF and CompactFlash Connector,” page 20 for more details.
