The following instructions set addresses in the RS, RE registers for zero overhead repeat control:
The GBR and VBR registers are the same as the previous SuperH registers. Four control bits
(DMX, DMY, RF1, and RF0 bits) and an RC counter have been added to the SR register. The RS,
RE, and MOD registers are new registers.
2.3
System registers consist of four 32-bit registers: high and low multiply and accumulate registers
(MACH and MACL), the procedure register (PR), and the program counter (PC). The multiply
and accumulate registers store the results of multiply and multiply and accumulate operations. The
procedure register stores the return address from the subroutine procedure. The program counter
indicates the address of the program executing and controls the flow of the processing. The PC
counter points to four bytes ahead of the instruction currently executing. These registers are the
same as the SuperH microprocessor registers.

Note:
System Registers
@(disp, PC); disp
@(disp, PC); disp
These are used only when executing an instruction that was supported
by SH-1 and SH-2. They are not used for multiplication instructions newly
added for the SH-DSP (PMULS).

(MACH) Multiply and accumulate
register low (MACL)
These are the registers for storing the
results of multiply and accumulate
operations. On the SH-2 CPU, MACH
has 32 valid bits. On the SH-1 CPU, only
the lower 10 bits of MACH are valid, and
data is sign extended to 32 bits when read.
Procedure register (PR)
This register is used to store the return
destination addresses for subroutine
procedures.
Program counter (PC)
The PC indicates the next four bytes
(two instructions) following the instruction
currently being executed.
