I think I still must be missing something. The image you submitted to our tech support was from page 12 of the XEM6310 User's Manual and doesn't have any mention of RZQ or ZIO that I can see. It also doesn't mention pins K7, Y2, or R7, W4 for that matter.
I just looked at our documentation online and did not find any references to pins R7 or W4. R7 is referenced, but only as a reference designator for setting up the Vbatt.
