Note 1: Recommended values of C1 and C2 are identical to the ranges tested Table 13-1 and Table 13-2.
2: Higher capacitance increases the stability of oscillator but also increases the start-up time.
3: Since each resonator/crystal has its own characteristics, the user should consult the resonator/crystal man-
ufacturer for appropriate values of external components.
4: Rs may be required in HS mode as well as XT mode to avoid overdriving crystals with low drive level speci-
fication.
