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