There are several possibilities but the following one generates the best code:

        struct lo_hi {
            unsigned char lo, hi;
        };

        hdt_lo = ((struct lo_hi*) &hdtable)->lo;
        hdt_hi = ((struct lo_hi*) &hdtable)->hi;

As most casts of this type, it is non portable, but I'm sure you don't care
about that:-)
