Why would it need to know those things (in this application)?
I would imagine that at the time of manufacture the barometer is calibrated to a known pressure for pass/fail testing and validating proper operation.
Having said that, once it's installed in the Naza it is simply an in-flight relative pressure measurement. As others have said it assigns the take-off pressure as Zero feet above the ground.
AGL, AMSL, serve no function to the flight controller in this application.
Sure atmospheric pressure changes would have an effect but how much change would you expect during the duration of a flight?
