So, speaking as the only person here who has read the spec sheet, this second pwm output gives absolute temperature. There are nice little graphs relating the reading to the temperature of the chip. In that regard it could be useful. I, however, have not tinkered with that particular output.
EDIT: I set up a calibration algorithm that gives an average of the first ten values it pulls from the gyro, and sets that as neutral (after 20 program loops to give it a chance to spinup) So I feel okay ignoring the temperature output.
