10.5 Run-Test/Idle State
This is a controller state between scan operations.
Once in this state, the controller remains in the state
as long as J-TMS is held low. The instruction reg-
ister and all test data registers retain their previous
state. When J-TMS is high and a rising edge is ap-
plied to J-TCK, the controller moves to the Select-
DR state.
10.6 Select-DR-Scan State
This is a temporary controller state and the instruc-
tion does not change in this state. The test data reg-
ister selected by the current instruction retains its
previous state. If J-TMS is held low and a rising
edge is applied to J-TCK when in this state, the
controller moves into the Capture-DR state and a
scan sequence for the selected test data register is
initiated. If J-TMS is held high and a rising edge
applied to J-TCK, the controller moves to the Se-
lect-IR-Scan state.
10.7 Capture-DR State
In this state, the Boundary Scan Register captures
input pin data if the current instruction is EXTEST
or SAMPLE/PRELOAD. The instruction does not
change in this state. The other test data registers,
which do not have parallel input, are not changed.

When the TAP controller is in this state and a rising
edge is applied to J-TCK, the controller enters the
Exit1-DR state if J-TMS is high or the Shift-DR
state if J-TMS is low.
10.8 Shift-DR State
In this controller state, the test data register con-
nected between J-TDI and J-TDO as a result of the
current instruction shifts data on stage toward its
serial output on each rising edge of J-TCK. The in-
struction does not change in this state. When the
TAP controller is in this state and a rising edge is
applied to J-TCK, the controller enters the Exit1-
DR state if J-TMS is high or remains in the Shift-
DR state if J-TMS is low.
10.9 Exit1-DR State
This is a temporary state. While in this state, if J-
TMS is held high, a rising edge applied to J-TCK
causes the controller to enter the Update-DR state,
which terminates the scanning process. If J-TMS is
held low and a rising edge is applied to J-TCK, the
controller enters the Pause-DR state. The test data
register selected by the current instruction retains
its previous value and the instruction does not
change during this state.
