Function Documentation

◆ __L1C_CleanInvalidateCache()

__STATIC_INLINE __ASM void __L1C_CleanInvalidateCache ( uint32_t op )

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

Parameters

[in] op 0 - 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.

◆ L1C_CleanDCacheAll()

__STATIC_INLINE void L1C_CleanDCacheAll ( void )

Clean the whole data cache.

◆ L1C_CleanDCacheMVA()

__STATIC_INLINE void L1C_CleanDCacheMVA ( void * va )

Clean data cache line by address.

Parameters

[in] va Pointer to data to clear the cache for.

◆ L1C_CleanInvalidateCache()

__STATIC_INLINE void L1C_CleanInvalidateCache ( uint32_t op )

Parameters

[in] op 0 - invalidate, 1 - clean, otherwise - invalidate and clean

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

◆ L1C_CleanInvalidateDCacheAll()
