correctly if there is no way in a design to stop (or slow) the clock during a SAMPLE/
PRELOAD instruction. If this is an issue, it is still possible to capture all other signals and
simply ignore the value of the CK and CK# captured in the boundary scan register.
Once the data is captured, it is possible to shift out the data by putting the TAP into the
shift-DR state. This places the boundary scan register between the TDI and TDO balls.
When the BYPASS instruction is loaded in the instruction register and the TAP is placed
in a shift-DR state, the bypass register is placed between TDI and TDO. The advantage of
the BYPASS instruction is that it shortens the boundary scan path when multiple devices
are connected together on a board.
The remaining instructions are not implemented but are reserved for future use. Do not
use these instructions.
