DescriptionInstruction CodeJTAG Instruction
• Allows you to capture and examine
a snapshot of signals at the device
pins during normal device
operation and permits an initial
data pattern to be an output at the
device pins.
• Use this instruction to preload the
test data into the update registers
before loading the EXTEST
instruction.
• Used by the SignalTap
™
II
Embedded Logic Analyzer.

SAMPLE/PRELOAD
• Allows you to test the external
circuit and board-level intercon-
nects by forcing a test pattern at the
output pins, and capturing the test
results at the input pins. Forcing
known logic high and low levels on
output pins allows you to detect
opens and shorts at the pins of any
device in the scan chain.
• The high-impedance state of
EXTEST is overridden by bus hold
and weak pull-up resistor features.
