 		 #160161 - Great!
Responding to: ???'s previous message
Thanks Kai, Michael,
I did this; "http://www.8052.com/forumchat/read/160153" because I thought as I am forced to use a 2 layer board , that could give a top and bottom plane a solid stitched GND connection, without VDD trace obstructing the plane . But I realise a bigger mistake commited regarding the loops being created . Michael you made the diagram great, can we use a Jumper from the VDD filter caps till we reach the ferrite bead where we are making AVDD, just to add some more continuity to the Ground plane.

Regards/
Ap
