    Assuming newVal contains the value you want to store in origVal. Do this for the 4 least significant bits:

    byte origVal = ???;
    byte newVal = ???
    orig = (origVal & 0xF0) + newVal;
    

    and this for the 4 most significant bits:

    byte origVal = ???;
    byte newVal = ???
    orig = (origVal & 0xF) + (newVal << 4);
