11. An internal power-on-reset is activated whenever power is applied to the device, or when coming out
12. Oscillator start-up time varies with the crystal parameters. This specification does not apply when
13. The wake-up period begins once the oscillator starts;
14. Calibration can also be initiated by pulsing CAL high while CONV=1.
15. Conversion time will be 1622/f clk if CONV remains high continuously.
