Hello together,

I'm just wondering what's the best way to do what the title says. I'm aware that the CTU(0) of the board (DEVKIT-MPC5744P) is probably my best option, BUT: every CTU0 EXT_IN pin (for an external interrupt source/button/signal) is hardwired/already in use for different parts on the board. So now I'm wondering what's the next best approach to get a interrupt signal to the CTU0 to start a ADC(0 or 1) conversion. Over FlexPWM or can I just use other pins on the board?

Thanks in advance,

Markus R.
