An error message will be displayed if:
• the result is not an accumulator register
• xval is a null value but xptr is not null
• yval is a null value but yptr is not null
Issues the 16-bit architecture's native signed divide support with the
same restrictions given in the “dsPIC30F/33F Programmer’s Reference
Manual” (DS70157). Notably, if the quotient does not fit into a 16-bit
result, the results (including remainder) are unexpected. This form of
the builtin function will capture both the quotient and remainder.
