#include <oc_mem_lld.h>

Data Fields
const void *	BaseAddress
	Base address of the region - this must point to the start of the region. More...

oC_MemorySize_t	Size
	Size of the region.

oC_Access_t	PrivilegedAccess
	Definition of access for privileged space (portable or core)

oC_Access_t	UserAccess
	Definition of access for user space.

oC_Power_t	Power
	Power state for the region (enabled or disabled)

bool	Cachable
	True if the region should be cacheable - If you set a region to be cacheable: When you load from that region, the cache is searched. More...

bool	Bufforable
	True if the region should be bufforable - Bufferable means whether a write to the address can be buffered. More...

uint32_t	RegionNumber
	(optional) Number of the region to configure. More...

bool	FindFreeRegion
	If true, the RegionNumber field is ignored and filled with the new value after configuration.

const void* BaseAddress

Only architecture supported values are allowed

bool Bufforable

When you do a write to a memory (e.g. a STR instruction) the write gets placed into a buffer in the processor. The buffer continually drains the writes to the memory system - allowing the core to continue with the next instructions. Processors often have multiple buffers, for example one between the pipeline and L1 data cache, another between the L1 and L2 caches, another for main memory....

bool Cachable

If the item is found, it is loaded from the cache. If the item is not found, a complete cache line including the required address is loaded. Some other cache line is evicted from the cache, unless there is an unused cache line available. When you save to that region, the cache is searched. If the item is found, the save is made to the cache. If the item is not found, the save is made to memory.

uint32_t RegionNumber

It is just ID index between 0 and oC_MCS_GetMaximumNumberOfRegions
