STM8S105C4T6, inverting the UART2_TX signal

Kmax18
Senior

I need an active high UART signal. Yes, the STM8S UART2_TX signal is active, but for hardware reasons I must invert the active low PCB output (UART2_TX). An easy solution would be a programmable STM8S feature to invert the signal. The reference manual does not list that option. Is that correct?

Thank you for your response.

Correct, unlike STM32, STM8 has no feature to invert UART TX.

Does it answer your question?
