Hi:Tomas
Thank you very much for your reply.
This one does solve my question, I just got the MC33771C chip manual, the old version I looked at before, as you said, I can find this.
However, I found a new question, can MC3371C dynamically identify the number of CIDs through software during the initialization process? The INIT register can only be programmed once, how can I determine which node's INIT[TPLx_TX_TERM] register should be set to 1 if I don't know which node is the last one.
Looking forward to your reply.
