Configuration Push Button (S5)

Board reference S5 is a push-button with a direct connection to the
Arria GX device’s CONFIGn signal that—upon pressing to drive low—
forces a reconfiguration of the FPGA from the on board flash memory.
The Arria GX device’s pin name associated with the CONFIGn signal is
V16

.

Pushing the S5 switch causes the FPGA to reload a configuration
from the on-board flash device.
