(Active-Low)
) grounds the FPGA PROG_B pin when pressed. This action
clears the FPGA. See the
Spartan-6 FPGA Data Sheet: DC and Switching Characteristics
(DS162)
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
for more details.
