Format:

DMTC0 rt, rd

Description:

The contents of general register

rt

are loaded into coprocessor register

rd

of the CP0.

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.

All 64-bits of the coprocessor 0 register are written from the general register source. The operation of DMTC0 on a

32-bit coprocessor 0 register is undefined.

Because the state of the virtual address translation system may be altered by this instruction, the operation of load

instructions, store instructions, and TLB operations immediately prior to and after this instruction are undefined.

Operation:

64 T: data ← GPR [rt]

T+1: CPR [0, rd] ← data

Exceptions:

Coprocessor unusable exception (In 64-bit/32-bit user and supervisor mode if CP0 not enabled)

Reserved instruction exception (32-bit user mode/supervisor mode)
