normal device operation, and permits an initial data pattern output at the device pins.
Allows the external circuitry and board-level interconnections 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 a selected device to adjacent devices during normal
device operation.
Selects the IDCODE register and places it between TDI and TDO, allowing the IDCODE
to be shifted out of TDO. Supported by the EPM9320A, EPM9400, EPM9480, and
EPM9560A devices only.
Selects the user electronic signature (UESCODE) register and allows the UESCODE to
be shifted out of TDO serially. This instruction is supported by MAX 9000A devices only.
These instructions are used when programming MAX 9000 devices via the JTAG ports
with the BitBlaster or ByteBlasterMV download cable, or using a Jam File (.jam), Jam
Byte-Code File (.jbc), or Serial Vector Format (.svf) File via an embedded processor or
test equipment.
MAX 9000 devices can be programmed on Windows-based PCs with an
Altera Logic Programmer card, the Master Programming Unit (MPU),
and the appropriate device adapter. The MPU performs continuity
checking to ensure adequate electrical contact between the adapter and
the device.

The MAX+PLUS II software can use text- or waveform-format test vectors
created with the MAX+PLUS II Text Editor or Waveform Editor to test a
programmed device. For added design verification, designers can
perform functional testing to compare the functional behavior of a
MAX 9000 device with the results of simulation.
Data I/O, BP Microsystems, and other programming hardware
manufacturers also provide programming support for Altera devices.
