Remapping Changing the address of physical memory or devices after the application has started
executing. This is typically done to permit RAM to replace ROM when the initialization
has been completed.
Reserved A field in a control register or instruction format is reserved if the field is to be defined
by the implementation, or produces Unpredictable results if the contents of the field are
not zero. These fields are reserved for use in future extensions of the architecture or are
implementation-specific. All reserved bits not used by the implementation must be
written as 0 and read as 0.
