WAVSEL = 10
Figure 32-8. WAVSEL= 00 with trigger
When WAVSEL = 10, the value of TC_CV is incremented from 0 to the value of RC, then auto-
matically reset on a RC Compare. Once the value of TC_CV has been reset, it is then
incremented and so on. See
It is important to note that TC_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 TC_CMR) and/or disable
the counter clock (CPCDIS = 1 in TC_CMR).
