Global Base Register (GBR): The global base register (GBR) is referenced as a base register in
GBR indirect addressing mode. At a reset, the GBR initial value is undefined.
Vector Base Register (VBR): The vector base register (VBR) can be accessed only in privileged
mode. If a transition from a state other than a reset state to exception handling state occurs, this
register is referenced as a base address of the branch destination. For details, refer to section 4,
Exception Handling. At a reset, VBR is initialized to H'00000000.
Figure 2.9 shows the control register configuration.
