    Note 1:
     Accuracy and dynamic performance tests performed after calibration.
    Note 2:
     Tested with 50% duty cycle. Duty cycles from 25% to 75% at 1.7MHz are acceptable.
    Note 3:
     See 
    External Clock section.
    Note 4:
     Guaranteed by design, not tested.
    Note 5:
     Measured in shutdown mode with CLK and SCLK low.
