and Programming Language (STAPL) Files (.jam), or Jam Byte-Code Files (.jbc).
The JTAG pins support 1.5-V, 1.8-V, 2.5-V, or 3.3-V I/O standards. The supported
voltage level and standard are determined by the V
The dedicated JTAG pins reside in Bank 1 of all MAX II devices.

CONFIG
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.
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 TDI and TDO pins,
which allows the BST data to pass synchronously through selected
devices to adjacent devices during normal device operation.
Selects the 32-bit USERCODE register and places it between the
TDI and TDO pins, allowing the USERCODE to be serially shifted
out of TDO. This register defaults to all 1’s if not specified in the
Quartus II software.
Selects the IDCODE register and places it between TDI and TDO,
allowing the IDCODE to be serially shifted out of TDO.
Places the 1-bit bypass register between the TDI and TDO pins,
which allows the boundary scan test data to pass synchronously
through selected devices to adjacent devices during normal device
operation, while tri-stating all of the I/O pins.
