18.8.1 Compare Output Mode and Waveform Generation

ATmega128RFA1
Figure 18-5. Compare Match Output Unit, Schematic
The Waveform Generator uses the COMnx1:0 bits differently in normal, CTC and PWM
modes. A setting of COMnx1:0 = 0 tells the Waveform Generator in all modes that no
action on the OCnx Register is to be performed on the next compare match. For
compare output actions in the non-PWM modes refer to Table 18-2. For fast PWM
mode refer to Table 18-3 and for phase-correct and phase-and-frequency-correct PWM
refer to Table 18-4.
A change of the COMnx1:0 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 FOCnx strobe bits.
Table 18-2 shows the COMnx1:0 bit functionality when the WGMn3:0 bits are set to a
normal or a CTC mode (non-PWM).
Table 18-2. Compare Output Mode, non-PWM
Table 18-3 shows the COMnx1:0 bit functionality when the WGMn3:0 bits are set to the
fast PWM mode.
