1 All Nexus timing relative to MCKO is measured from 50% of MCKO and 50% of the respective signal. Nexus timing specified
at VDD = 1.08 V to 1.32 V, VDDE = 3.0 V to 3.6 V, VDD33 and VDDSYN = 3.0 V to 3.6 V, TA =TL to TH, and CL = 30 pF with
DSC = 0b10.
2 The Nexus AUX port runs up to 82 MHz (pending characterization). Set NPC_PCR[MKCO_DIV] to correct division depending
on the system frequency, not to exceed maximum Nexus AUX port frequency.
3 See Notes on t
cyc on Figure 16 and Table 28 in Section Section 4.11.1 Clocking.
4 MDO, MSEO, and EVTO data is held valid until next MCKO low cycle.
5 Lower frequency is required to be fully compliant to standard.
6 The RDY pin timing is asynchronous to MCKO. The timing is guaranteed by design to function correctly.
