Push Buttons and LEDs

Before using the Blackfin FPGA EZ-Extender, follow the steps in
EZ-Extender Setup" on page
Figure 2-4 shows the locations of all push buttons and LEDs. The follow-
ing sections describe the associated functionality of all the push buttons
and LEDs.

Program Push Button (SW1)

The program push button,
push button can be used as a hard reset—the FPGA must be completely
re-programmed once

PB1 Push Button (SW3)

The push button,
PB1
switch with a connected debounce circuit eliminates the need to re-create
it in the FPGA. The push button connects to pin
