WAVSEL = 00
When WAVSEL = 00, the value of CV is incremented from 0 to 0xFFFF. Once 0xFFFF has been
reached, the value of CV is reset. Incrementation of CV starts again and the cycle continues.
An external event trigger or a software trigger can reset the value of 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 CMR) and/or disable the coun-
ter clock (CPCDIS = 1 in CMR).
