Memory Aliasing

Aliasing is a feature present in MCUs that enables the user to map one address space to another.

In Metalware, you can alias one RAM region to another RAM region. Let’s consider the following example:

• ⁍ of size ⁍
• ⁍ of size ⁍

If we aliased ⁍ to ⁍, the following would occur:

• Any write to ⁍ would be readable from ⁍.
• Any write to ⁍ would be readable from ⁍.

Metalware enforces the following constraints:

• ⁍
• ⁍
• ⁍ may not be an alias.
