(2) SAMPLE/PRELOAD instruction
implies, the SAMPLE/PRELOAD instruction provides two functions.
does not disconnect the system logic from the IC pins. SAMPLE is executed in the
Capture-DR state. It is mainly used to capture the values of the IC’s I/O pins on the rising
edge of TCK during normal operation. Figure 3.2.8 shows the flow of data for the SAMPLE
phase of the SAMPLE/PRELOAD instruction.
This instruction targets the boundary scan register between TDI and TDO. As its name
SAMPLE allows the input and output pads of an IC to be monitored. While it does so, it

PRELOAD allows the boundary scan register to be reset before any other instruction is
selected. For example, prior to selection of the EXTEST instruction, PRELOAD is used
to load reset data into the boundary scan register. PRELOAD permits data shifting of
the boundary scan register without interfering with the normal operation of the system
logic. Figure 3.2.9 shows the data flow for the PRELOAD phase of the
SAMPLE/PRELOAD instruction.
