INTERFACES
SAMPLE
The sample instruction samples all the device inputs and outputs. For this
instruction, the boundary scan register is placed between TDI and TDO. Primary
device inputs and outputs can be sampled by loading the boundary scan register
using the Capture-DR state. The sampled values can then be viewed by shifting
the boundary scan register using the Shift-DR state.
IDCODE
The identification instruction is used to connect the identification register between
TDI and TDO. The device's identification code can then be shifted out using the
Shift-DR state.
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 on output TDO
using the Shift-DR state.
