sman...keep in mind "power supply" and "power source" when commenting......there can only be one power supply per-say......however, there can be many power sources off that supply.

In this case we are discussing the power source 2( blue) ... power source 1 (green) and distributive 1.1 (green) and how they interact....engaging the control circuitry.

There is more at stake here than the VPP to the flash socket....even though that is a focus to show a difference between prior art and e.Digitals methods in having absolute control over VPP.....where status quo did not. VPP high voltage issues were a problem, and in the past.....way past...RB past....lol..... I contributed comments about it.

anyway ....I hope there's a little insight in there for you...It should get you thinking about the order of things.
