When WAVSEL = 11, the value of CV is incremented from 0 to RC. Once RC is reached, the
value of CV is decremented to 0, then re-incremented to RC and so on. See
A trigger such as an external event or a software trigger can modify CV at any time. If a trigger
occurs while CV is incrementing, CV then decrements. If a trigger is received while CV is decre-
menting, CV then increments. See
RC Compare can stop the counter clock (CPCSTOP = 1) and/or disable the counter clock
(CPCDIS = 1).
