The boundary scan register allows testing of board inter-connectivity. The boundary 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 primary input, TDI and
forced onto all digital outputs.

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.
