I just had another look at your Renesas SoC and indeed, the register 
default is
to set IO3 high if not used. Mh. I still think 3,3,3,3 is the saner 
default.
But I might be wrong. Hard to tell, as the sample size is just Micron 
and Atmel
for now. And it's still unclear to me why the Atmel isn't working with 
3,3,3,1.
