Instruction Code
Cyclone II devices also use the JTAG port to monitor the logic operation
of the device with the SignalTap
devices support the JTAG instructions shown in
Allows a snapshot of signals at the device pins to be captured 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.
Places the 1-bit bypass register between the

devices to adjacent devices during normal device operation.

Places the 1-bit bypass register between the
which allows the BST data to pass synchronously through selected
devices to adjacent devices during normal device operation while
holding I/O pins to a state defined by the data in the boundary-scan
register.
