This enables a setup of different unit times, even if the internal RC oscillator varies by
±20%. Of course, timing values that are too low could clash with timing requirements of
the application and should therefore be avoided, but in principle it is possible to adjust
the timer unit for a more precise protocol timing. The output characteristic depends on
the external load, the wiring, as well on the pull-up voltage and the temperature. All these
parameters have considerable influence to find the proper unit time setup.
