Position of pin 1 on VQG100 package

I just waded through all the available data sheets and app notes on the XC2C128

Coolrunner in the VQG100 package, but for the life of me I cannot determine without doubt where

the Pin 1 is.  Close to the small or the large circle? The large circle looks more inviting,

but there seemed to be devices with the small circle only.

If it weren't for the unsoldering of the wreck, I might simply try it.

Thanks & best regards,

Gerhard Hoffmann

It's the small circle. I took the 50% chance.
I can program the chip.

Maybe someone could update the DS.

I'm not the package expert, but does this help?
