[Bug]: USART with a single line

[giuliomoro]

Bug Summary

In CubeMx, the assignment of pins when trying to use a UART with a single data line is not OK

Detailed Description

When setting a USART to Asynchronous and then setting Advanced Parameters->Data direction to Receive only or Transmit only, both pins stay selected and there's no way of unassigning one. For instance, if I set it to Receive only, I would expect the TX pin to be unassigned.

Expected Behavior

If I set it to Receive only, I would expect the TX pin to be unassigned.

Actual Behavior

both pins stay assigned and cannot be unassigned

Environment

CubeMx 6.16.1

Severity

None
