SAMPLE/PRELOAD. SAMPLE/PRELOAD is a mandatory instruction for the IEEE 1149.1 specification. This
instruction supports two functions. The digital I/Os of the device can be sampled at the boundary scan register
without interfering with the normal operation of the device by using the Capture-DR state. SAMPLE/PRELOAD also
allows the device to shift data into the boundary scan register through JTDI using the Shift-DR state.
EXTEST. EXTEST allows testing of all interconnections to the device. When the EXTEST instruction is latched in
the instruction register, the following actions occur. Once enabled by the Update-IR state, the parallel outputs of all
digital output pins are driven. The boundary scan register is connected between JTDI and JTDO. The Capture-DR
samples all digital inputs into the boundary scan register.
BYPASS. When the BYPASS instruction is latched into the parallel instruction register, JTDI connects to JTDO
through the 1-bit bypass test register. This allows data to pass from JTDI to JTDO not affecting the device’s normal
operation.
IDCODE. When the IDCODE instruction is latched into the parallel instruction register, the identification test
register is selected. The device identification code is loaded into the identification register on the rising edge of
JTCLK following entry into the Capture-DR state. Shift-DR can be used to shift the identification code out serially
through JTDO. During Test-Logic-Reset, the identification code is forced into the instruction register’s parallel
output.
HIGHZ. All digital outputs are placed into a high-impedance state. The bypass register is connected between JTDI
and JTDO.
CLAMP. All digital output pins output data from the boundary scan parallel output while connecting the bypass
register between JTDI and JTDO. The outputs do not change during the CLAMP instruction.

9.3 JTAG Scan Registers
IEEE 1149.1 requires a minimum of two test registers—the bypass register and the boundary scan register. An
optional test register, the identification register, has been included in the design and is used with the IDCODE
instruction and the Test-Logic-Reset state of the TAP controller.
Bypass Register
The bypass register is a single 1-bit shift register used with the BYPASS, CLAMP, and HIGHZ instructions that
provides a short path between JTDI and JTDO.
Identification Register
The identification register contains a 32-bit shift register and a 32-bit latched parallel output. This register is
selected during the IDCODE instruction and when the TAP controller is in the Test-Logic-Reset state. The device
ID code always has a 1 in the LSB position. The next 11 bits identify the manufacturer’s JEDEC number and
number of continuation bytes, followed by 16 bits for the device and 4 bits for the version.
Boundary Scan Register
The boundary scan register contains a shift register path and a latched parallel output for all control cells and digital
I/O cells.
