WAVSEL = 2
When CMRn.WAVSEL is two, the value of CVn is incremented from zero to the value of RC,
then automatically reset on a RC Compare. Once the value of CVn has been reset, it is then
incremented and so on. See

It is important to note that CVn can be reset at any time by an external event or a software trig-
ger if both are programmed correctly. See

In addition, RC Compare can stop the counter clock (CMRn.CPCSTOP) and/or disable the
