50.6.12.3 WAVSEL = 01
When WAVSEL = 01, the value of TC_CV is incremented from 0 to 2
16
-1 . Once 2
16
-1 is reached, the value of
TC_CV is decremented to 0, then reincremented to 2
16
-1 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 cannot be programmed to generate a trigger in this configuration.
At the same time, RC Compare can stop the counter clock (CPCSTOP = 1) and/or disable the counter clock
(CPCDIS = 1).
