FPGA_PROG_B Pushbutton SW4 (Active-Low)
This switch grounds the FPGA's PROG_B pin when pressed. This action clears the FPGA.
See the Virtex-6 FPGA Data Sheet for more information on clearing the contents of the
FPGA. [Ref 4]
SYSACE_RESET_B Pushbutton SW3 (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 24 for more details.
