| Code model |
- default
- Large - Functions are called with a long call, allowing access
to the full memory range of the device. Branches internal to the
function are limited by the range of the various branch
instructions.
- Small - Functions are called using the relative call. Call
targets must be within +/- 32K words of the call site; otherwise
a linker error will occur directing the use of the large code
model.

| Scalar model |
- default
- Large - No assumptions are made about the location of static and
external scalars.
