A DPERR (data parity error) occurs on the slave0 node on the a2b network. How to analyze and handle it? At present, the ad2425w is the master and the ad2426w is the slave. The differential signal of the a2b bus meets the requirements. The slave 0 node can obtain the correct chipid, vendor and other information. DPERR will appear for both external power supply and bus power supply.
