Hi Sir,
My customer facing a issue that the the pin10 output have a ring waveform as attachment and cause the UART link fail
I provide the schematic and waveform"Fail"
CH1(RTS_S): pin13
Customer told us that if they remove the ESD component it will ok.
What we should suggest customer to do to fix this issue?
What parameter of the ESD component that customer should choose to fix this issue?
Thanks,
Patrick
