• Manufacturer Part Number: HD6417144
• Description: 32-Bit RISC Microcomputer SuperHTM RISC engine Family/SH7144 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

2.1
• General-register architecture
• Sixty-two basic instructions
• Eleven addressing modes
2.2
The register set consists of sixteen 32-bit general registers, three 32-bit control registers, and four
32-bit system registers.
2.2.1
The sixteen 32-bit general registers (Rn) 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 recovering the status register (SR) and program counter (PC) in exception processing is
accomplished by referencing the stack using R15.
