    The result of an integer divide by an unsigned is undefined.
    This causes unexpected results when writing negative values
    into the limit registers.
    Maintain the shunt_resistors variables as signed integer to avoid
    the problem. Also, for simplicity and ease of use, clamp shunt
    resistor value on writes instead of rejecting bad values.
