ISO1452: [ISO1452] Full-duplex and Half-duplex reference circuit for RS485

Hi Sir,

as the datasheet "Isolated RS-485 Transceiver Reference Design" "SLLA453–May 2019"

I want to confirm the circuit full-duplex compatible with half-duplex or not?

I have RS422 full-duplex schematic as below and confirmed with TI FAE but we will chnage application to RS485.

The RS485 should be half-duplex protocol?If yes, I need to modify the schematic to half-duplex?

Thanks
