Registers of the DRS4 are accessed through
the sytem ram (Addr8). It is a 32bit system,
so the address format is u32.
_ a note here _ : Each register is 32bit. This means for
the Addr8 (8 refers to bits) a register occupies 4 bytes,
so a new register will be the previous register + 4.
If the register is the same as another, then the register
holds different fields for the different bits in the register.
