2.1
The register set consists of sixteen 32-bit general registers, four 32-bit control registers, and four
32-bit system registers.
2.1.1
Figure 2.1 shows the general registers.
The sixteen 32-bit general registers are numbered R0 to R15. General registers are used for data
processing and address calculation. R0 is also used as an index register. Several instructions have
R0 fixed as their only usable register. R15 is used as the hardware stack pointer (SP). Saving and
restoring the status register (SR) and program counter (PC) in exception handling is accomplished
by referencing the stack using R15.
Notes: 1. R0 functions as an index register in the indexed register indirect addressing mode and indexed GBR indirect
2. R15 functions as a hardware stack pointer (SP) during exception processing.
addressing mode. In some instructions, R0 functions as a fixed source register or destination register.
