STCTEST
The single transport chain instruction is used to test out the TAP controller and
the boundary scan register during production test. When this instruction is the
current instruction, the boundary scan register is connected between TDI and
TDO. During the Capture-DR state, the device identification code is loaded into
the boundary scan register. The code can then be shifted out output, TDO using
the Shift-DR state.
INTEST
The internal test instruction is used to exercise the device's internal core logic.
When this instruction is the current instruction, the boundary scan register is
connected between TDI and TDO. During the Update-DR state, patterns shifted
in on input, TDI are used to drive primary inputs. During the Capture-DR state,
primary outputs are sampled and loaded into the boundary scan register.
