Hello!

I have a question regarding the bcc_775a_read_32ct example of the MBDT S32k344.

Does anyone know what are this numbers and where can I find them:

(I know that they are the addresses and can be configures through the external tool but I cannot make the connection and find them)

Are they related to the number of the address of the datasheet of the image I atteched below?

Also, where does this faults mean? What do they verify? Where can I fin this?

On the other hand, I have been trying to read the voltages of 4 devices from 1 BCC chain but I don´t how to change the adress of each. I have been doing it as shown in the picture below: changing the device adress and then adding another data store memory for the cell voltages of the second device. However, I cannot see anything in FreeMaster I cannot find the adress of the second device. Am I doing it right?

If I am working with 2 device do I nedd to change the number ' Bcc775aDriver/Bcc775aChain1DevNum-4'  to 2? What does this mean?

Finally, How can I do an Stateflow to periodically switch the Device Address and each step time to read data from other BCC in a round robin approach is there any example of that?

-Do I need to initialize all the devices or just with one inizialization process is enough?

-Do I need to add a memory data for each cell voltage device?  

Thank you very much in advance !!
