I think this is connected to some last DRAM address stuff. DMA may not work if 
this is incorrect. Consult some similar datasheet 
jjj.ivn.pbz.gj!ra!qbjaybnqf!qngnfurrgf!puvcfrgf!QF_PA400_118.mvc
It may be the last bank ending address??? Perhaps this must be copied from 
function 3 maybe?

Perhaps is something translating configuration cycles?
