RS485 Driver Enable

Is there somewhere a better description about this feature, than there is in the f070 reference manual? Maybe an example?

I don't quite seem to understand how it's supposed to work. Or does CubeMX handle it somehow incorrectly?

Could it affect DMA somehow?

I have two USARTs in use, both using similar DMA (mostly shared code). The other one is typical RS232 and the other is RS-485 (really RS232 with DE-signal, the line driver is not yet used). The typical RS232 works fine, but the RS-485 doesn't seem to have receive DMA enabled.
