Section 13 Timer Z
Figure 13.23 shows another example of operation in PWM mode. The output signals go to 0 and
TCNT is reset at compare match A, and the output signals go to 1 at compare match B, C, and D
(TOB, TOC, and TOD = 0, POLB, POLC, and POLD = 1).

Figure 13.23 Example of PWM Mode Operation (2)
Figures 13.24 (when TOB, TOC, and TOD = 0, POLB, POLC, and POLD = 0) and 13.25 (when
TOB, TOC, and TOD = 0, POLB, POLC, and POLD = 1) show examples of the output of PWM
waveforms with duty cycles of 0% and 100% in PWM mode.
