I will use TCD0 in split mode, to have two 8 bit timers.
I want to generate an event from one of these on underflow, which is said to be supported in the manual.

But when I look for the particular event source for CHnMUX, I don't see anything specific for the Type 2 timers. There should be two event sources listed, one for the low timer and one for the high timer.

Any clues?

I'll try experimenting with TCD0 as event source to see what happens...

I've found that the TCD0 over/underflow event value, is also the TCD0L underflow event value.

EVSYS.CH7MUX=0xD0; // Event CH7 = TCD0L underflow

I'm not sure about the TCD0H event, but for now I only need the event from the low timer.
