STATE
DESCRIPTION
Exit1-IR
This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to
enter the Update-IR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the
controller enters the Pause-IR state. The test data register selected by the current instruction retains its previous value and
the instruction does not change during this state.
The pause state allows the test controller to temporarily halt the shifting of data through the instruction register. The test
data register selected by the current instruction retains its previous value and the instruction does not change during this
state. The controller remains in this state as long as TMS is low. When TMS goes high and a rising edge is applied to TCK,
the controller moves to the Exit2-IR state.
This is a temporary state. While in this state, if TMS is held high, a rising edge applied to TCK causes the controller to
enter the Update-IR state, which terminates the scanning process. If TMS is held low and a rising edge is applied to TCK, the
controller enters the Shift-IR state. The test data register selected by the current instruction retains its previous value and the
instruction does not change during this state.
The instruction shifted into the instruction register is latched into the parallel output from the shift-register path on the falling
edge of TCK. When the new instruction has been latched, it becomes the current instruction. The test data registers selected
by the current instruction retain their previous value.
