Also overrun errors occur if the transmit data rate exceeds the receive FIFO servicing latency that will occur if you are accessing the FIFO with the 2 channels at the same time, but it's hard to tell if that is the reason of your issue. Could you share the configuration you used?</P><P></P><P>Regards,</P><P>Darío</P></BODY></HTML> Tue, 17 Oct 2017 23:35:43 GMT https://community.nxp.com/t5/Other-NXP-Products/SC16IS752IPW/m-p/713835#M5280 darioarias 2017-10-17T23:35:43Z
