Datasheet
A.2.1
Instruction Register
The IXF1002 JTAG test logic instruction register is a 3-bit scan-type register that is used to
program the JTAG machine to the appropriate operating mode. Its contents are interpreted as test
instructions.
Table A-1
lists the instructions register.
A.2.2
Bypass Register
The bypass register is a 1-bit shift register that provides a single-bit serial connection between the
tdi and tdo signals. This register is used when the instruction register is set to bypass mode or after
powerup.
A.2.3
Boundary-Scan Register
The boundary-scan register consists of cells located on all the pads. This register provides the
ability to perform board-level interconnection tests by shifting data inside through tdi and outside
through tdo. It also provides additional control and observation of the IXF1002 pins. For example,
the IXF1002 boundary-scan register can observe the output enable control signals of the I/O pads.

EXTEST mode (mandatory instruction)
.
Test data is shifted into the IXF1002
boundary-scan register and then transferred in
parallel to the output pins.

1
Sample-preload mode (mandatory instruction)
.
Test data is loaded in parallel from the input pins
into the IXF1002 boundary-scan register and then
shifted out for examination.

Tristate mode (optional instruction)
.
Allows the IXF1002 to enter the power-saving
mode. In this mode, all the port pads are tristated.

Bypass mode (mandatory instruction)
.
Allows the test features on the IXF1002 test logic
to be bypassed. Bypass mode is selected
automatically when power is applied.
