mc9s12p bandgap and temp sensor

I am trying to write software using the internal temp. sensor and voltage ref.  I am able to read the result, but does anyone know what a/d out should be for a given temp?  Or what the band gap reference voltage will be?  The only spec I can find is the temp sensor slope is 4.0-6.5 mV/deg C.  Does that mean 0 deg C = 0 mV?  I'm operating at 5V.
