Recommended Call Convention
AVR32
Table 2-9.
The compiler vendor is free to define a call convention, but seen from a hardware point of view,
there are some recommendations on how the call convention should be defined.
Register R12 is intended as return value register in connection with function calls. Some instruc-
tions will use this register implicitly. For instance, the conditional ret instruction will move its
argument into R12.
