Question

Write an MSP430 assembly language program that implements the
following algorithm:
a macro called "vdot" that calculates the "dot product" of two vectors "a" and "b",
implemented as “arrays” (following the “C” language convention), of 3
elements. the macro should receive 2 pointers to the first element of each vector and
return the result in R13.

I have another file where I save my vectors called, "vars.c" here I save:

int a[] = { 14, 65, 9}

int b[] = {72,51, 22}
