Interrupts and events
Figure 14-15. Port override for Timer/Counter 0 and 1
The T/C can generate both interrupts and events. The Counter can generate an interrupt on
overflow/underflow, and each CC channel has a separate interrupt that is used for compare or
capture. In addition the T/C can generate an error interrupt if any of the CC channels is used for
capture and a buffer overflow condition occurs on a capture channel.
Event will be generated for all conditions that can generate interrupts. For details on event gen-
eration and available events refer to
