1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.

2. Not 100% tested. Specified by design characterization.

3. This specification is based on the capabilities of the ITP debug port, not on processor silicon.

4. Referenced to the rising edge of TCK.

5. Referenced to the falling edge of TCK.

6. TRST# must be held asserted for 2 TCK periods to be guaranteed that it is recognized by the processor.

7. Specification for a minimum swing defined between TAP V

to V

. This assumes a minimum edge rate of

0.5 V/ns.

8. It is recommended that TMS be asserted while TRST# is being deasserted.

T57: TDI, TMS Hold Time 7.5 ns 2-19 4,7

T58: TDO Clock to Output Delay 0 7.5 ns 2-19 5

T59: TRST# Assert Time 2 T
