Hi, i am using this for FDC2112 , not 2212. Need a couple of clarifciations :-

Does the getReading16 function return 12 MSBs of the result, or all 16 bits.
What is the conversion required to changed the result to Capacitance value at the sensor assuing internal oscillator frequecy of 43.4 Mhz

Reason for the query is that while i am getting data back, the values are way to high, and not corresponding to the resonant frequency expected.
