Hello,

I want to invert the logic of Transmit line of UART. I tried setting SCTR-->DOCFG to 1. But still, line state in Idle state is always High and not low.

Can you please suggest some way to invert the transmit line of UART(XMC4500)?

Hi Rahul,

Are you trying with XMC4500 AppKit? I've tried with setting "USIC0_CH0 -> SCTR |= USIC_CH_SCTR_DOCFG_Msk" and the line kept "Low" during idle. Pls give a try, thanks.

Best regards,
Sophia
