When WAVSEL = 10, the value of TC_CV is incremented from 0 to the value of RC, then automatically 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 pro-
grammed 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).
