    Is the PWM output (OCMP1A) on Port F bit 4 effected by the DDR & the OR or does the the PWM write to the Pin/Pad directly.

    I want an open drain output from the PWM.

    Is this achievable?

    When an alternate function is used , alternate function takes priority our standard I/O programming. When signal is coming from on-chip peripheral, that pin is automatically configured in O/P mode(push-pull or open-drain) depending up on the peripheral used. So, it is not possible to change this configuration.
