System register
Reading from this register is only enabled between a DBTRAP exception (exception handler address
0000 0060
upon ILGOP and ROM Correction detections (refer to “Interrupt Controller (INTC)“ on page 187 and “ROM
Correction Function (ROMC)“ on page 331).

System registers control the status of the CPU and hold interrupt information.
Additionally, the program counter holds the instruction address during program
execution.
To read/write the system registers, use instructions LDSR (load to system
register) or STSR (store contents of system register), respectively, with a
specific system register number (regID) indicated below.
The program counter states an exception. It cannot be accessed via LDSR or
STSR instructions. No regID is allocated to the program counter.
STSR 0, r2
Stores the contents of system register 0 (EIPC) in general purpose register r2.
The table below gives an overview of all system registers and their system
register number (regID). It shows whether a load/store instruction is allowed (
for the register or not (
