#define ARM_MPU_ACCESS_ (   TypeExtField,
  IsShareable,
  IsCacheable,
  IsBufferable 
)
Value:
((((TypeExtField) << MPU_RASR_TEX_Pos) & MPU_RASR_TEX_Msk) | \

MPU Memory Access Attributes

Parameters
TypeExtFieldType extension field, allows you to configure memory access type, for example strongly ordered, peripheral.
IsShareableRegion is shareable between multiple bus masters.
IsCacheableRegion is cacheable, i.e. its value may be kept in cache.
