class SpiModuleBase(SpiModuleBaseNative, InstrumentChannel):
    """
    Defines an abstract base class for SPI modules. All module drivers
    should inherit from this class.

    This class defines no actual functionality but rather serves to provide
    a common interface shared among all modules.

    Parameters
    ----------
    parent
        Reference to the :class:`~qblox_instruments.SpiRack` parent object.
        This is handled by the
        :func:`~qblox_instruments.SpiRack.add_spi_module` function.
    name : str
        Name given to the InstrumentChannel.
    address : int
        Module number set on the hardware (set internally on the module
        itself with a jumper).

    Returns
    ----------

    Raises
    ----------
