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.}
