Programming Notes

Execution of this instruction is privileged.

The DCR number (DCRN) specified in the assembler language coding of the mfdcr instruction refers to a

DCR number. The assembler handles the unusual register number encoding to generate the DCRF field.

Architecture Note

The specific numbers and definitions of any DCRs are outside the scope of both the PowerPC Book-E archi-

tecture and the PPC440x5 core. Any DCRs are defined as part of the chip-level product incorporating the

PPC440x5 core.
