CTU - How to verify for which input signal, the software triggers are generated

Hi everyone,

 

I am working with Cross Triggering Unit of MPC5643L. I have a question regarding the TGS input signal. If I selects 4 input signals for trigger generation. It will be OR-ed to get the MRS in case of triggered mode or ES will be generated in case of sequential. 

 

I linked the generated triggers to ADC. Now, How to verify for which input signal, the software triggers are triggering the ADC?

 

since, register to select the type of input signal is only available, How can we know for which signal, the triggering is done.

 

It is easy to say if only one input signal is selected for trigger generation. What if more than one input signal is selected?

 

In example provided in the nxp forum, PWM-ADC triggering, only one input signal has been selected 

For eg,

Consider I have selected REAL PWM CHANNEL 0 EVEN FALLING EDGE, REAL PWM CHANNEL2  ODD FALLING EDGE and  REAL PWM CHANNEL 1 EVEN RISING EDGE. The trigger for ADC is enabled for all the 8 triggers.

Now how to check for which input signal, the ADC triggering is done?

 

Awaiting for the answer.
