LPC845 Low-power oscillator temperature

Datasheet says low-power oscillator frequency is +-40 % over process and temperature. May drift while counting due to temperature changes.

 

=> Are there any documents available specifying the influence of _just_ the temperature? Measuring/Calibration at a specific temperature is not that difficult. But how strong will the temperature change the frequency? 1 % per 30K? 5 % per 30K? 10 % per 30K? ...

VDD will have influence as well (but under my control); actually I'm interested only in temperature.
