uint32_t * |
addr, |
|
|
int32_t |
dsize |
|
) |

- Parameters
-
[in] | addr | address (aligned to 32-byte boundary) |
[in] | dsize | size of memory block (in number of bytes) |
The function cleans a memory block of size dsize [bytes] starting at address address. The address is aligned to 32-byte boundry.
The function cleans and invalidates the entire data cache.
__STATIC_INLINE void SCB_CleanInvalidateDCache_by_Addr |

- Parameters
-
[in] | addr | address (aligned to 32-byte boundary) |
[in] | dsize | size of memory block (in number of bytes) |
The function invalidates and cleans a memory block of size dsize [bytes] starting at address address. The address is aligned to 32-byte boundry.
The function turns off the entire data cache.
- Note
- When disabling the data cache, you must clean (SCB_CleanDCache) the entire cache to ensure that any dirty data is flushed to external memory.
The function turns on the entire data cache.
- Note
- Before enabling the data cache, you must invalidate the entire data cache (SCB_InvalidateDCache), because external memory might have changed from when the cache was disabled.
-
After reset, you must invalidate (SCB_InvalidateDCache) each cache before enabling it.
The function invalidates the entire data cache.
- Note
- After reset, you must invalidate each cache before enabling (SCB_EnableDCache) it.
