Maybe I'm misunderstanding, but that functionality is implemented in another component. The register bank only records the category of each register and implements the memory-mapped register functionality.
This list of registers and their categories are then imported in separate components which sit between incoming writes and the register bank. The advantage is that everything which describes the properties of the registers is in a single file. You don't have to look in three different places to find out how a register behaves.
