HI,

I just wanted to know if it is possible to invert the UART lines (non active low)?

Kind regards

Added this question also for another device. MSP430FR6989: Is it possible to setup the UART to inverted signal lines (nonactive low) - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums. I just need the answer for MSP430G2755

Hi Tunguskar,

There is no signal inversion available for the UART in these devices.

If you just care about the idle state, you could reconfigure the pin as an output pin and drive it low when not using UART. If you want full inversion you could use a software UART, or you could add a hardware inverter.

Best Regards,
