NOTES:
5. AC tests performed with C
L
= 40pF, I
OL
= 5mA, and I
OH
= -5mA. Input reference level for CLK, TRST is 2.0V, all other inputs 1.5V. Test V
IH
=
3.0V, V
IHC
= 4.0V, V
IL
= 0V; V
OH
= V
OL
= 2.5V.
6. These are asynchronous inputs; setup and hold times must only be maintained in order to predict which clock cycle they take effect internally.
7. Timing must only be maintained when Update bit is active in control word data being loaded.
8. Special Timing relationship between TCK and CLK is required for Test Instructions RUNBIST, EXTEST and INTEST.
9. All inputs except TRST, and only when TCK is driving internal clock.
10. Controlled via design or process parameters and not directly tested. Characterized upon initial design and after major process and/or design
changes.
