3.7.2 Processor Option
The -mprocessor=device option selects the target device for
which to compile. A list of all supported devices can be found the compiler release notes.
Note that the name must be in upper case, for example, -mprocessor=ATSAME54P20A.
This option selects only the target device; it does not indicate what version of the device
support files to use. Additionally, use the -mdfp option (see Dfp Option) for this purpose.
