Timer/Counter Timing
Diagrams

ATmega162(V/U/L)
The Timer/Counter is a synchronous design and the timer clock (clk
shown as a clock enable signal in the following figures. The figures include information
on when interrupt flags are set, and when the OCRnx Register is updated with the
OCRnx buffer value (only for modes utilizing double buffering). Figure 55 shows a timing
diagram for the setting of OCFnx.

Figure 56 shows the same timing data, but with the prescaler enabled.

Figure 57 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.
