MPC5674F EQADC Continuous Mode vs Streaming Mode

Hello,

I hope you are well. I am working on EQADC of MPC5674F. I have developed a code where EQADC_A is working in Continuous Mode and converting the Channel 0, 1 and 2 in order.

When I was reading the MPC5674FRM; I thought that there is no need to fill CFIFO again and again in Continuous Mode, however in practice I couldn't get new ADC results without filling the CFIFOs again.

After I read more carefully the MPC5674FRM; I noticed that the specifications that I am expecting from the Continuous Mode, actually in Streaming Mode.

Can you give me brief explanation of difference between Continuous Mode and Streaming Mode? Also, I have understood that there is no need to filling CFIFOs again and again in Streaming Mode, however in Continuous Mode we need to fill CFIFOs in order to read new ADC results. Am I correct?

Best Regards,

Mert.

Yes, you understand it right.

In the past I made example code, even with descriptive PDF document:

Hope it helps
