tTPD and tRPD minimum is 0sec; therefore, PDN can be applied at the same time as VDD18 and VDD33.
tTPLL0 is the time from “both PDN=High and HTPDN=Low“ moment to Training pattern ignition.
HTPDN could transit from High to Low under PDN=High condition at THCV215, which is different from what
Figure 17 indicates but is natural situation.
