Figure 13-11. Timer/Counter Timing Diagram, Setting of OCFnx, with Prescaler (f
clk_I/O/8)
Figure 13-12 shows the count sequence close to TOP in various modes. When using phase and
frequency correct PWM mode the OCRnx Register is updated at BOTTOM. The timing diagrams
will be the same, but TOP should be replaced by BOTTOM, TOP-1 by BOTTOM+1 and so on.
The same renaming applies for modes that set the TOVn Flag at BOTTOM.
Figure 13-12. Timer/Counter Timing Diagram, no Prescaling
Figure 13-13 shows the same timing data, but with the prescaler enabled.
