2.1
The SH7729R has the same registers as the SH-3. In addition, the SH7729R also supports the
same DSP-related registers as in the SH2-DSP. The basic software-accessible registers are divided
into four distinct groups:
With the exception of a number of DSP registers, all of these registers are 32-bit width. The
general registers are accessible from user mode, with R0–R7 banked to provide each processor
mode access to a separate set of R0–R7 registers (i.e. R0–R7_BANK0, and R0–R7_BANK1). In
privileged mode, the register bank bit (RB) in the status register (SR) defines which set of banked
registers (R0–R7_BANK0 or R0–R7_BANK1) are accessed as general registers, and which are
accessed only by LDC/STC instructions.
The control registers can be accessed by LDC/STC instructions. The GBR, RS, RE, and MOD
registers can also be accessed in user mode. Control registers are:
The system registers are accessed by the LDS/STS instructions (the PC is software-accessible, but
is included here because its contents are saved in, and restored from, SPC in exception handling).
The system registers are:
General registers
Control registers
System registers
DSP registers
SR: Status register
SSR: Saved status register
SPC: Saved program counter
GBR: Global base register
VBR: Vector base register
RS: Repeat start register (DSP mode only)
RE: Repeat end register (DSP mode only)
MOD: Modulo register (DSP mode only)
MACH: Multiply and accumulate high register
MACL: Multiply and accumulate low register
PR: Procedure register
PC: Program counter
