25. If external MCLK is used, then duty cycle must be between 45% and 55% to maintain this specification.
26. Specified using 10% and 90% points on wave-form of interest. Output loaded with 50 pF.
27. Oscillator start-up time varies with crystal parameters. This specification does not apply when using an
