Description

Function Documentation

__STATIC_INLINE __ASM void __L1C_CleanInvalidateCache ( uint32_t  op)
Parameters
[in]op0 - invalidate, 1 - clean, otherwise - invalidate and clean
Deprecated:
Use generic L1C_CleanInvalidateCache instead.

Generic mechanism for cleaning/invalidating the entire data or unified cache to the point of coherency.

The parameter op defines which cleaning/invalidation strategy should be used:

  • 0 - Cache is invalidated using DCISW register.
  • 1 - Cache is cleaned using DCCSW register.
  • other - Cache is invalidated and cleaned using DCCISW register.
__STATIC_INLINE void L1C_CleanDCacheAll ( void  )
__STATIC_INLINE void L1C_CleanDCacheMVA ( void *  va)
Parameters
[in]vaPointer to data to clear the cache for.
__STATIC_INLINE void L1C_CleanInvalidateCache ( uint32_t  op)
Parameters
[in]op0 - invalidate, 1 - clean, otherwise - invalidate and clean
