TAP Controller

Figure 19.2 shows the internal states of the TAP controller. State transitions basically conform to

the JTAG standard.

Figure 19.2 TAP Controller State Transitions

Note:

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

value is sampled at the rising edge of the TCK signal and is shifted at the falling edge of

the TCK signal. For details on change timing of the TDO value, see section 19.4.3, TDO

Output Timing. The TDO pin is high impedance, except in the shift-DR and shift-IR

states. A transition to the Test-Logic-Reset state is made asynchronously with TCK by

driving the

TRST signal 0.
