This mandatory instruction provides a minimum length serial path (1 bit) between TDI and TDO
when no test operation of the component is required.
This mandatory instruction allows testing of off-chip circuitry and board level interconnections.
This mandatory instruction can be used to take a sample of the inputs during normal operation of
the component. It can also be used to preload data values into the latched outputs of the boundary
scan register.
This optional instruction is useful for testing when not all ICs have BST. This instruction addresses
the bypass register while the boundary scan register is in external test mode.
This optional instruction will provide information on the components manufacturer, part number and
version number.
This optional instruction allows testing of the internal logic (no customer support available).
This private instruction allows testing by the manufacturer (no customer support available).
