@Olivier'Ölbaum'Scherler: In this mode (Waveform Generation Mode 7) the register OCR2A is used to set the pulse period (via the "TOP" value). You cannot use the same register to set the pulse length. If you set the pulse length with OCR2B, then the PWM signal can only be output on pin OC2B.

However, I don’t understand why it’s not possible to output the frequency on the OC2A pin. Indeed, there seems to be the same mode for OC2A in table 17-3: Clear OC2A on compare match, set OC2A at BOTTOM, (non-inverting mode). I tried and it doesn’t work, as you said, but I can’t find the part of the docs that say why. | |
