Timer PWM Dithering for each CCRx register?

[GAnde.1]

The STM32G4 series offers dithering to enhance the PWM ratio. My question is, if dithering can be used on ALL the compare channels of the same timer?

Specifically, we generate a center-aligned PWM with two output compare channels 180° shifted. CCR1 and CCR2 are changed simultaneously to change both duty cycle. Can dithering be applied to both registers?

That's no 'G4-specific feature, it's just software regularly changing the duty cycle.

Okay so hardware dithering is a new feature in G4 timers.

As dithering is nothing more than changing duty cycle, so... why not?

According to RM, yes; you can't avoid it working on all CCRx registers.
