possible to capture all other signals and simply ignore the
value of the CLK 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.
Note that since the PRELOAD part of the command is not
implemented, putting the TAP to the Update-DR state while
performing a SAMPLE/PRELOAD instruction will have the
same effect as the Pause-DR command.
BYPASS
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 the TDI and TDO balls. The
advantage of the BYPASS instruction is that it shortens the
boundary scan path when multiple devices are connected
together on a board.
Reserved
These instructions are not implemented but are reserved for
future use. Do not use these instructions.
