Accuracy and temperature characteristics of adc reference voltage

Hi, 

What is the accuracy and temperature characteristics of SAADC's Internal Reference (= 0.6V)?

thank you

    Let me check it additionally.

    1. Is the room temperature 25 ° C?

    2. Does "0.2% at room temperature" mean that room tempreature always deviates by 0.2% (it becomes 0.6012V)? Or is it 0.2% / ° C?

    3. If Question 2 is the former, please tell me the temperature characteristics (% / ° C).

    4. If Question 2 is the latter, "+ 2 / -3% over full operating temperature" does not hold, so please tell me the details. The operating temperature is -40 to 85 ° C, so if it is 0.2% / ° C, it will shift by 0.2% * 125 = 25%.

    5. Is there a dependency on Supply Voltage?
