HIGH DENSITY VT/TU MAPPER
AND M13 MULTIPLEXER
bit delay from primary input, TDI to primary output, TDO. The device
identification register contains the device identification code.
The boundary scan register allows testing of board inter-connectivity. The
boundary scan register consists of a shift register placed 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.

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.
