Section 2 Register Configuration
Section 2 Register Configuration
The register set of the SH-1 and SH-2 consists of sixteen 32-bit general registers, three 32-bit
control registers and four 32-bit system registers.
The SH-DSP maintains upward compatibility with the SH-1 and SH-2 microprocessors on the
object code level. To this end, it has the same registers as the SuperH microprocessors, with the
addition of several other registers. Three control registers have been added: the repeat start register
(RS), the repeat end register (RE), and the modulo register (MOD). Six other registers have also
been added: the DSP status register (DSR), which is a system register, and eight DSP data
registers (A0, A1, X0, X1, Y0, Y1, M0, and M1).
The general registers are used the same as in the SH-1 and SH-2 when SuperH type instructions
are involved. With DSP type instructions, however, they are used as address registers and index
registers for accessing memory.
2.1
General Registers
There are 16 general registers (Rn) numbered R0–R15, which are 32 bits in length (figure 2.1).
General registers are used for data processing and address calculation. R0 is also used as an index
register. Several instructions use R0 as a fixed source or destination 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.
