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...
