Thank you for feedback, I think I wasent to clear in my explanation. I understand the part of the array, but I got lost further. I can see in the code that the input is used, please see attached screenshoot. But when I cross reef the symbol name I don`t get up something write to it, it must some logic somwhere who "unpack" the erray and load and transfer each bit (digital input), to the symbol names example IO_STB_DiTB33.2 ?? Is the only way to browse in the code to find the code who do the decoding og the word in the erray to bits?
