start-up time. These values are for design guidance only. A series resistor, Rs, may
be required in HS mode as well as XT mode to avoid overdriving crystals with low
drive level specification. Since each crystal has its own characteristics, the user
should consult the crystal manufacturer for appropriate values of external compo-
nents or verify oscillator performance.
