Detailed Description
System ACE Controller Reset
Figure 1-2
callout [19]
Pressing pushbutton SW2 (RESET) resets the System ACE controller. Reset is an
active-Low input.
Configuration Address DIP Switches
Figure 1-2
callout [20]
DIP switch SW3 selects one of the eight configuration bitstream addresses in the
CompactFlash memory card. The switch settings for selecting each address are shown in
Table 1-2
.

FPGA U1 PROG Pushbutton, INIT LED and DONE LED
Figure 1-2
callout [21]
Pressing the U1 PROG push button (SW5) grounds the active-Low program pin of the
FPGA. The INIT LED (DS20) lights during FPGA initialization. The DONE LED (DS56)
indicates the state of the DONE pin of the FPGA. When the DONE pin is High, the DONE
LED lights indicating that the FPGA is successfully configured.
