reset state is released, keep the TMS input signal asserted through five consecutive rising
edges of TCK input. Keeping TMS asserted maintains the Reset state.
The state transition diagram of the TAP controller is shown in Figure 3.2.6. Each arrow
between states is labeled with a 1 or 0, indicating the logic value of TMS that must be set
up before the rising edge of TCK to cause the transition.
