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