Options for the CPU cache mode that define the CPU mapping of the resource.

enum MTLCPUCacheMode
```

## Topics

### Specifying the cache mode

[`MTLCPUCacheMode.defaultCache`](/documentation/Metal/MTLCPUCacheMode/defaultCache)

The default CPU cache mode for the resource, which guarantees that read and write operations are executed in the expected order.

[`MTLCPUCacheMode.writeCombined`](/documentation/Metal/MTLCPUCacheMode/writeCombined)

A write-combined CPU cache mode that is optimized for resources that the CPU writes into, but never reads.
