Compare Output Mode and Waveform Generation
Figure 15-9. Compare Match Output Unit, Schematic
The Waveform Generator uses the COM4x1:0 bits differently in Normal mode and PWM modes.
For all modes, setting the COM4x1:0 = 0 tells the Waveform Generator that no action on the
OCW4x Output is to be performed on the next Compare Match. For compare output actions in
the non-PWM modes refer to
on page
A change of the COM4x1:0 bits state will have effect at the first Compare Match after the bits are
written. For non-PWM modes, the action can be forced to have immediate effect by using the
FOC4x strobe bits.
