2.1.2 Control Registers
The control registers consist of four 32-bit registers: the status register (SR), the global base
register (GBR), the vector base register (VBR), and the jump table base register (TBR).
The status register indicates instruction processing states.
The global base register functions as a base address for the GBR indirect addressing mode to
transfer data to the registers of on-chip peripheral modules.
The vector base register functions as the base address of the exception handling vector area
(including interrupts).
The jump table base register functions as the base address of the function table area.
