21.7.1 Compare Output Mode and Waveform Generation
8266B-MCU Wireless-03/11
Figure 21-7. Compare Match Output Unit, Schematic
The Waveform Generator uses the COM2x1:0 bits differently in normal, CTC, and PWM
modes. Setting the COM2x1:0 = 0 for all modes tells the Waveform Generator that no
action on the OC2x Register is to be performed on the next compare match. For
compare output actions in the non-PWM modes for fast PWM mode and for phase
correct PWM refer to section
A change of the COM2x1:0 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 FOC2x strobe bits.
The following table shows the COM2x1:0 bit functionality when the WGM02:0 bits are
set to a normal or CTC mode (non-PWM).
Table 21-3. Compare Output Mode, non-PWM Mode
Table 17-3 shows the COM2x1:0 bit functionality when the WGM21:0 bits are set to fast
PWM mode.
