The breathing pattern can be clipped, as shown in the following figure, so that the breathing effect appears to pause at
its maximum and minimum brightnesses:

CLIPPING EXAMPLE
Full on
Max Duty Cycle
Full off
Min Duty Cycle
The clipping periods at the two extremes can be adjusted independently, so that for example an LED can appear to
breathe (with a short delay at maximum brightness) followed by a longer “resting” period (with a long delay at minimum
brightness).
The brightness can also be changed in a non-linear fashion, as shown in the following figure:
