1.
aaa Guaranteed by design.
2. Assumes a 25 pF load on TDO. Output timing derates at 0.072 ns/pF of extra load applied.
3. For correct data latching, the I/O signals (from the core and the pads) must be set up and held with respect to the rising edge
of TCK in the CAPTURE-DR state of the SAMPLE/PRELOAD and EXTEST instructions.
4. Assumes that the data outputs are loaded with the AC test loads.
5. TDO enable time applies when the TAP controller enters the Shift-DR or Shift-IR states.
6. TDO disable time applies when the TAP controller leaves the Shift-DR or Shift-IR states
7. Data output enable time applies when the boundary scan logic is used to enable the output drivers.
8. Data output disable time applies when the boundary scan logic is used to disable the output drivers.
9. TCK may be stopped indefinitely in either the low or high phase.
