8.2 TAP CONTROLLER
The TAP controller is responsible for interpreting the sequence of logical values on the TMS
signal. It is a synchronous state machine that controls the operation of the JTAG logic. The
state machine is shown in Figure 8-2. The value shown adjacent to each arc represents the
value of the TMS signal sampled on the rising edge of the TCK signal.
