Transformer un code issu d'une plateforme de 32 bit a un code compilable en msp430 qui utilise 16 bit

j'ai un code écrit en dev c++ pour une plateforme de 32 bit je veux compilé ce code on micro contrôleur msp430 qui est sur 16 bit.
quels sont les modification que je doit apporté a mon code autre que le changement de type de variables de word en unsigned int ?aidez moi svp c urgent.
