Figure 24.2 TAP Controller State Transitions

Note:

The transition condition is the TMS value at the rising edge of TCK. The TDI value is

sampled at the rising edge of TCK; shifting occurs at the falling edge of TCK. For details

on change timing of the TDO value, see section 24.4.3, TDO Output Timing. The TDO is

at high impedance, except with shift-DR and shift-IR states. During the change to

TRST =

0, there is a transition to test-logic-reset asynchronously with TCK.
