Figure 30.3 shows the internal states of the TAP controller. The state transitions basically conform
to the JTAG standard.
• State transitions occur according to 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 shifted at the falling edge of
• The TDO value is changed at the falling edge of the TCK signal. The TDO signal is in a Hi-Z
• A transition to the Test-Logic-Reset by clearing TRST to 0 is performed asynchronously with
