WAVSEL = 01
Figure 31-9. WAVSEL = 10 With Trigger
When WAVSEL = 01, the value of CV is incremented from 0 to 0xFFFF. Once 0xFFFF is
reached, the value of CV is decremented to 0, then re-incremented to 0xFFFF and so on. See
Figure
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 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).
