FIGURE 39. DUTY CYCLE vs RS at 32kHz
NOTE: Figure 39 (Duty Cycle vs RS at 32kHz) should only be used for 32kHz crystals. RS may be used at other frequencies to adjust Duty
Cycle but experimentation will be required to find an appropriate value. The RS value will be proportional to the effective series resis-
tance of the crystal being used.
