Hi Everyone,

I am working with the CTU module of MPC5643L. I am able to test PWM-ADC triggering through CTU and eTimer-ADC triggering through CTU. I want to test GPIO-ADC triggering through CTU.


I tried testing by configuring the external falling edge event and enable interrupt in SIUL with External Falling Edge as TGS input selection. I also configured CTU registers for triggering ADC (ADC Command related and trigger compare & counter registers). But it doesnt work for me.


How to trigger ADC by GPIO through CTU?


I have no idea about what to do (i.e what to configure ) in SIUL module for GPIO - ADC triggering through CTU?


 Can anybody guide me for this case?
