KL03 DAC output pin for signal generation

Hi,

I have a very basic question. I want to generate a signal with the FRDM-KL03 board and give this generated analog waveform say to some external circuit.

 

I am using KDS software and following the ADC uTasker guide (page 12).

Now, the Kinetis SDK Application User Guide says that: "Normally, the DAC0_OUT is internally connected to the ADC0_SE23 (DAC0_OUT is a source of ADC0_SE23),".

 

So, is the output of the DAC going in input to the ADC? 

And if I want to "see" the generated signal, to which jumper on the FRDM-KL03 board should I connect? From the KL03 Sub-family manual (table page 99) it seems to be the J4-PTA9? But I am not sure. I mean I tried but I could not see the waveform

 

Thank you
