10.3.3
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.
10.3.4
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.
10.3.5
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 con-
nected 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.
