Function Documentation

void L1CACHE_InvalidateCodeCacheByRange	(	uint32_t	address,
		uint32_t	size_byte
	)

Parameters

address	The physical address of cache.
size_byte	size of the memory to be invalidated.

Note

Address and size should be aligned to "L1CODCACHE_LINESIZE_BYTE". The startAddr here will be forced to align to L1CODEBUSCACHE_LINESIZE_BYTE if startAddr is not aligned. For the size_byte, application should make sure the alignment or make sure the right operation order if the size_byte is not aligned.

		uint32_t	size_byte
	)

Parameters

address	The physical address of cache.
size_byte	size of the memory to be cleaned.

Note

Address and size should be aligned to "L1CODEBUSCACHE_LINESIZE_BYTE". The startAddr here will be forced to align to L1CODEBUSCACHE_LINESIZE_BYTE if startAddr is not aligned. For the size_byte, application should make sure the alignment or make sure the right operation order if the size_byte is not aligned.

void L1CACHE_CleanInvalidateCodeCacheByRange	(	uint32_t	address,
