  1. That surprises me a bit, I assumed that there would be no such "hard" requirements on virtual registers, and that that would be the motivation to have the feature to begin with. Looking at my problem from the other direction then, if I have several addressblocks inside a memorymap, the databus and the registers being 32 bit. Then there is a special addressblock that contains some wider (e.g. 128 bit, or even more) datastructures. Those are also updated over the 32 bit bus, the updates are made safe somehow, e.g. through buffered writes, or some more global synchronisation (like disable th
  2. If I create "virtual registers", that is, registers defined inside an addressBlock with usage "memory", does the size of the register still need to be <= the addressBlock width, as mandated by "SCR 7.5 RegisterSizeWithinBlock"?
