I have connected a R/G Led between two port pins (PD4,PD5) so that I choose between red/green color.
Now, I'd like to extend that with pwm so that the leds can show yellow/orange.
I haven't yet tried it, but it looks like using TCA in split mode with the second PWM output inverted would work.
However, it looks like it's only possible to use WO[n] + WO[n+3]. It would be possible to use PD2 (=WO2) and PD5 (=WO5), but not PD4 and PD5. Is it possible to use use channel2 und route WO2 to port PD4 with CCL? I have not yet used CCL and would appreciate some hints how this can be done (if it's possible at all).
