THE INSTRUCTION REGISTER
instruction is to be executed. Information contained in the instruction includes the
mode of operation (either normal mode, in which the device performs its normal
logic function, or test mode, in which the normal logic function is inhibited or
altered), the test operation to be performed, which of the four data registers is
to be selected for inclusion in the scan path during data-register scans, and the
source of data to be captured into the selected data register during Capture-DR.
TEST DATA REGISTER
Boundary Scan register and Device ID register.

path. When the bypass register is selected by an instruction, the shift register
stage is set to a logic zero on the rising edge of TCLK when the TAP controller

1) to store test data that is to be applied externally to the device output pins, and/
or 2) to capture data that appears internally at the outputs of the normal on-chip
logic and/or externally at the device input pins.

JTAG INSTRUCTION REGISTER
device when the TAP controller is in the Shift-IR state. The instruction is decoded
to perform the following:
16 different possible instructions. Instructions are decoded as follows.
a complete description refer to the IEEE Standard Test Access Port Specification
(IEEE Std. 1149.1-1990).
EXTEST
boundary-test mode and selects the boundary-scan register to be connected
between TDI and TDO. During this instruction, the boundary-scan register is
accessed to drive test data off-chip via the boundary outputs and receive test
data off-chip via the boundary inputs. As such, the EXTEST instruction is the
workhorse of IEEE. Std 1149.1, providing for probe-less testing of solder-joint
opens/shorts and of logic cluster function.
SAMPLE/PRELOAD
a normal functional mode and selects the boundary-scan register to be
connected between TDI and TDO. During this instruction, the boundary-scan
register can be accessed via a data scan operation, to take a sample of the
functional data entering and leaving the device. This instruction is also used to
preload test data into the boundary-scan register before loading an EXTEST
instruction.
IDCODE
mode and selects the optional device identification register to be connected
between TDI and TDO. The device identification register is a 32-bit shift register
containing information regarding the device manufacturer, device type, and
version code. Accessing the device identification register does not interfere with
the operation of the device. Also, access to the device identification register
should be immediately available, via a TAP data-scan operation, after power-
up of the device or by otherwise moving to the Test-Logic-Reset state.
