Figure 38. Nexus output timing

3.22.4

External interrupt timing (IRQ pins)

NOTES:

1 JTAG specifications in this table apply when used for debug functionality. All Nexus timing relative to MCKO is

measured from 50% of MCKO and 50% of the respective signal.

2 MDO, MSEO, and EVTO data is held valid until next MCKO low cycle.

3 The system clock frequency needs to be three times faster than the TCK frequency.
