![Christian Lütke-Stetzkamp](/assets/img/avatar_default.png)
Currently the base address for all io operations is hidden behind a macro, REG_ADD. This macro uses the symbol "base" as the base address and all functions set base = host->base. This is hard to read, so the whole wrapping is removed and host->base is directly inserted in the io access.
