SDR Store Doubleword Right (2/3) SDR
An address error exception is not occurred that specify address is not located in doubleword boundary.
This operation is defined in 64-bit mode or in 32-bit kernel mode. Execution of this instruction in 32-bit user or
supervisor mode causes a reserved instruction exception.
Operation:
