I heard back from the vendor today; they've acknowledged the limitation and
are considering adding support for 0% in a future ROM spin. In the meantime,
they've agreed to describe the high-impedance behavior in the data sheet as
well as include the pull-down resistor in an example schematic.

Oh wow, seems like a good vendor then. :-)

Option (3) seems like overkill for such a simple PWM, and ultimately doesn't
add any value because I don't want to allow option (1) behavior in any case.
Whether the PWM is disabled because it is truly disabled or to simulate a 0%
duty cycle as in option (2), the pull-down is ultimately required regardless
of whether or not the data sheet happens to go into such detail.

Actually I like option 3 best.
 

Based on your other feedback, I'm moving forward under the impression that
you'll still accept option (2); please let me know if I have misunderstood
(thank you for being flexible).

Yeah, that's fine. If in the end it shows that this is a bad idea we can
still change to (3).

Best regards
Uwe
