ASIC functions
§ Offset Calibration: Calibration of capacitive sensor offset
§ Span Calibration Calibration of capacitive sensor span
§ Self test of ASIC(Build in switch capacitance circuit to test the ASIC)
§ Self test of sensor(by applying a voltage to the capacitive accelerometer, the self test function test the integrity of the sensor during field operation
§ Bandwidth adjustment (low pass 500Hz or 2000Hz), 50Hz with external capacitor
§ Clock Frequency adjustment
