Move Between Control File and Register File MVC
3-181 Instruction SetSPRU733
Execution if (cond) src2 → dst
The MVC instruction executes only on the B side (.S2).
Refer to the individual control register descriptions for specific behaviors and
restrictions in accesses via the MVC instruction.
Unit in use
Instruction Type Single-cycle
Any write to the ISR or ICR (by the MVC instruction) effectively has one delay
slot because the results cannot be read (by the MVC instruction) in the IFR until
two cycles after the write to the ISR or ICR.
