9 description:
10 The Altera Freeze Bridge Controller manages one or more freeze bridges.
11 The controller can freeze/disable the bridges which prevents signal
12 changes from passing through the bridge. The controller can also
13 unfreeze/enable the bridges which allows traffic to pass through the bridge
14 normally.
