Hi all, The OP was incomplete (sorry Olin) and requires some additional explanations: The mapping concerns all 0x?7F and 0x?FF addresses; included the last 0x3FF that seems in fact to be isolated from the other addresses and named "testreg". So I suppose there is a special behavior on this 0x3FF address that some MC software uses? Or what else?
