I have found a strange issue with a ATtiny817 Xplained Pro development board. I wanted to get a delayed pulse, so the idea was to use the event system to trigger a TCD fault from TCA which then starts a TCD sequence. This works "mostly", i.e. with at least one combination of TCA and TCD input frequencies I get a jumpy output signal. With an ATtiny3217 I do NOT observe these issues.
I have attached a ZIP file with the Atmel studio project and some screenshots to explain what I observe. A short explanation of the necessary changes to get stable or unstable output is in main.c, line 68. I think the rest is self-explaining.
Could someone with the same type of development board check if the same behaviour can be observed? Or is it just an issue with my board? Any help is appreciated.
