TLB Synchronize
The tlbsync instruction is provided by the PowerPC Book-E architecture to support synchronization of TLB
operations between processors in a coherent multi-processor system. Since the PPC440x5 core does not
support coherent multi-processing, this instruction performs no operation, and is provided only to facilitate
code portability.
If instruction bit 31 contains 1, the contents of CR[CR0] are undefined.

Programming Note

operation.
