[Icc-avr] Casting

[Johannes Assenbaum]

As someone mentioned before, this is only safe for Little Endian, but as AVRs are Little Endian, there will be no problem with iccavr.

Btw: Shortest code (no optimisation enabled) will be with source value casted.

Data[7] = ((unsigned int)(Channel_One) >> 8);
Data[8] = ((unsigned int)(Channel_One));

Best regards,
Johannes
