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 theFlushCodeCache
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.
