KV4x: trigger ADC at different times over a PWM period

I'm using the Simulink Toolbox for Model-Based Design with KV4x but now there is a question which is placed here better.

As I asked here https://community.nxp.com/thread/469445#comment-993599 I want to know if it is possible to trigger the ADC at different times over one pwm period with KV4x.


I found out that with an additional pre-Trigger in the PDB_Config block the End of Scan Interrupt occures two times, so with every pre Trigger all configured samples are read. This is not what I want !

So in simultaneous mode the both converters adca and adcb should read one specific sample pair with each trigger but not directly after each other.


For example:

Trigger0 - ADCA: I_phA ; ADCB: I_phB

Trigger1 - ADCA: U_dcb ; ADCB: I Temp
