I use CW 4.5 for s12x
if i declare a function like it
void f(char i, char j)
and the same function like that
void f(int i, int j)
What is the best déclaration for the micro (for speed)? I don't really need 16 bit variables but i am translating old functions to a new application for 9s12x and a lot of functions are declared with int for char really needed. If i change all my declarations functions, will my program will work faster?
