To copy the special purpose LO register to a GPR.
GPR[rx] = LO
The contents of special register LO are loaded into GPR rx.
None
GPR[Xlat(rx)] = LO
None
In the MIPS I, II, and III architectures, the two instructions which follow the MFHI must not moodify the HI register.
If this restriction is violated,the result of the MFHI is UNPREDICTABLE. This restriction was removed in MIPS
IV and MIPS32, and all subsequent levels of the architecture.
