30.5 Operation
30.5.1 TAP
Control
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 TCK signal.
•
The TDO value is changed at the falling edge of the TCK signal. The TDO signal is in a Hi-Z
state other than in the Shift-DR or Shift-IR state.
•
A transition to the Test-Logic-Reset by clearing
TRST
to 0 is performed asynchronously with
the TCK signal.
