mary input, TDI to primary output, TDO. The device identification register con-
tains the device identification code.
The boundary scan register allows testing of board inter-connectivity. The bound-
ary scan register consists of a shift register place in series with device inputs and
outputs. Using the boundary scan register, all digital inputs can be sampled and
shifted out on primary output, TDO. In addition, patterns can be shifted in on pri-
mary input, TDI and forced onto all digital outputs.
TAP Controller
The TAP controller is a synchronous finite state machine clocked by the rising
edge of primary input, TCK. All state transitions are controlled using primary
input, TMS. The finite state machine is described below.
