Hi,
I had a contractor who found a reset bug in one of our Mega103
applications. Apparently, if the Z register is incremented and rolls
over to zero, under some conditions a reset can result. His fix was
to manually increment each half of the register. I don't know if this
behaviour is documented.
Cheers
Scott
