When WAVSEL = 00, the value of TC_CV is incremented from 0 to 0xFFFF. Once 0xFFFF has been reached, the value
of TC_CV is reset. Incrementation of TC_CV starts again and the cycle continues. See 

.

An external event trigger or a software trigger can reset the value of TC_CV. It is important to note that the trigger may
occur at any time. See 

RC Compare cannot be programmed to generate a trigger in this configuration. At the same time, RC Compare can stop
the counter clock (CPCSTOP = 1 in TC_CMR) and/or disable the counter clock (CPCDIS = 1 in TC_CMR).
