Figure 13.3 TAP Controller Status Transition
Note: The transition condition is the TMS value at the rising edge of TCK. The TDI value is
sampled at the rising edge of the TCK and shifted at the falling edge of the TCK. The
TDO value changes at the falling edge of the TCK. In addition, TDO is high-impedance
state in a state other than Shift-DR or Shift-IR state. If TRST is 0, Test-Logic-Reset state
is entered asynchronously with the TCK.
