``analogWriteResolution(bits)``. ``new_range`` may be from 15...65535
or ``bits`` may be from 4...16.

The function ``analogWriteMode(pin, value, openDrain)`` allows to sets
the pin mode to ``OUTPUT_OPEN_DRAIN`` instead of ``OUTPUT``.

**NOTE:** The default ``analogWrite`` range was 1023 in releases before
3.0, but this lead to incompatibility with external libraries which
depended on the Arduino core default of 256. Existing applications which
