Nexus Debug Interface
Figure 13. Nexus Output Timing
Table 27. Nexus Debug Port Timing1
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. Nexus timing specified at VDDE =3.0–5.5V, TA =TL to TH, and CL =30pF
with SRC = 0b11.
