        `callback_parsed` (optional) (function reference) callback function to invoke on receipt of feed data. This is
        equivalent to `callback` except the dict includes the `parsed` key which holds the set of values in a
        [PointDataObject](./Point.m.html#IoticAgent.IOT.Point.PointDataObject) instance. If both
        `callback_parsed` and `callback` have been specified, the former takes precedence and `callback` is only called
        if the point data could not be parsed according to its current value description.

        `NOTE`: `callback_parsed` can only be used if `auto_encode_decode` is enabled for the client instance.
