36.4.1
Figure 36.2 shows the internal states of the TAP controller. State transitions support the JTAG
standard.
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 36.4.3, 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.
