There are the following comments at the above.
"The issue with connecting VPP to VDD is that there is a possibility of some current path between the supplies based on how this is shorted and during power up/down."
"The current path is possible if there is a voltage delta between VPP and VDD during a power up/down. During steady state, there will not be any current."
I understand that connecting VPP to VDD is possible if the current path during power up/down is not detrimental.
Is my understanding correct?
Best regards,
