Nexus Timing
Figure 10. Nexus Output Timing
Table 21. Nexus Debug Port Timing1
1 JTAG specifications apply when used for debug functionality. All Nexus timing relative to MCKO is measured from 50% of
MCKO and 50% of the respective signal. Nexus timing specified at VDD = 1.35–1.65 V, VDDE = 2.25–3.6 V,
VDD33 and VDDSYN = 3.0–3.6 V, TA = TL to TH, and CL = 30 pF with DSC = 0b10.
