and examined during normal device operation, and permits an
initial data pattern to be output at the device pins. Also used by
the SignalTap II embedded logic analyzer.
Allows the external circuitry and board-level interconnects to be
tested by forcing a test pattern at the output pins and capturing
test results at the input pins.
Allows a snapshot of signals at the device pins to be captured
