Move Control Word to Coprocessor 2

Purpose:

Move Control Word to Coprocessor 2

To copy a word from a GPR to a Coprocessor 2 control register.

Description: 

 CP2CCR[Impl] = GPR[rt]

Copy the low word from GPR rt into the Coprocessor 2 control register denoted by the Impl field. The interpretation of the Impl field is left entirely to the Coprocessor 2 implementation and is not specified by the architecture.

Restrictions:

The result is UNPREDICTABLE if rd specifies a register that does not exist.

Operation: 

temp = GPR[rt]31..0
CP2CCR[Impl] = temp

Exceptions:

Coprocessor Unusable, Reserved Instruction
