2.1
The register set consists of sixteen 32-bit general registers, three 32-bit control registers, and four
32-bit system registers.
2.1.1
General registers Rn consist of sixteen 32-bit registers (R0–R15). General registers are used for
data processing and address calculation. Register R0 also functions as an index register. For some
instructions, the R0 register must be used. Register R15 functions as a stack pointer to save or
recover status registers (SR) and program counter (PC) during exception processing.
2.1.2
Control registers consist of the 32-bit status register (SR), global base register (GBR), and vector
base register (VBR). The status register indicates processing states. The global base register

R0 functions as an index register
in the indexed register addressing
mode and indirect indexed GBR
addressing mode. In some instruc-
tions, R0 functions as a source
register or a destination register.
R15 functions as a stack pointer (SP)
during exception processing.
