WAVSEL = 10
1790A–ATARM–11/03
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 Figure 145.
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 Figure 146.
In addition, RC Compare can stop the counter clock (CPCSTOP = 1 in TC_CMR) and/or dis-
able the counter clock (CPCDIS = 1 in TC_CMR).
