Capture Phase
In the capture phase, the
signals at the pin, OEJ and
OUTJ, are loaded into the
capture registers. The CLOCK
signals are supplied by the TAP
controller's CLOCKDR output.
The data retained in these
registers consists of signals
from normal device operation.
Shift and Update Phases
In the shift phase, the
previously captured signals at
the pin, OEJ and OUTJ, are
shifted out of the boundary-scan
register through the TDO pin using
CLOCK. As data is shifted out,
the patterns for the next test
can be shifted in through the
TDI pin.
In the update phase, data is
transferred from the capture
registers to the update
registers using the UPDATE
clock. The data stored in the
update registers can be used
for the EXTEST instruction.
Altera Corporation
The SAMPLE/PRELOAD instruction mode allows you to take a snapshot of device data
without interrupting normal device operation. However, this instruction is most often
used to preload the test data into the update registers prior to loading the EXTEST
instruction.
