Enum cortex_mpu::cortex_m4::MemoryAttributes

pub enum MemoryAttributes {
    StronglyOrdered,
    Device {
        shareable: bool,
    },
    Normal {
        shareable: bool,
        cache_policy: CachePolicy,
    },
}

Describes memory type, cache policy, and shareability.

Variants

StronglyOrdered

Shareable, non-cached, strongly-ordered memory region.

Device

Non-cached device peripheral region.

Fields of Device

shareable: bool

Whether the region is accessible by more than one bus master (eg. a DMA engine or a second MCU core).

Normal

Normal memory region (ie. "actual" memory, such as Flash or SRAM).

Fields of Normal

shareable: bool

Whether the region is accessible by more than one bus master (eg. a DMA engine or a second MCU core).

cache_policy: CachePolicy

How this region should be cached (?).
