WAVSEL = 10
Figure 31-7. WAVSEL= 00 with trigger
When WAVSEL = 10, the value of CV is incremented from 0 to the value of RC, then automati-
cally reset on a RC Compare. Once the value of CV has been reset, it is then incremented and
so on. See
It is important to note that CV can be reset at any time by an external event or a software trigger
if both are programmed correctly. See
In addition, RC Compare can stop the counter clock (CPCSTOP = 1 in CMR) and/or disable the
counter clock (CPCDIS = 1 in CMR).
