Routines

Manipulating the Processor Caches

The system software provides routines that allow you to enable, disable, and flush the processor caches. Before you call any of the routines described in this section, be sure to check that the trap _HWPriv is implemented. The only exception is the FlushCodeCache procedure, which is available whenever the processor has a cache that can be flushed.

WARNING

If you call these routines and _HWPriv isn't implemented, your application will crash.
