The Figure 206 below shows how to generate some more complex waveforms, using the 4
available compare units and the toggle mode.
Figure 206. Complex symmetric waveform in up-down counting mode
The Figure 207 shows how to generate an asymmetric waveform. In this case, it must be
noticed that it is necessary to have compare 2 value greater than compare 1 value for the
waveform to be asymmetric.

Note: For asymmetric operation, it is required that CMP2 > CMP1.
