9 description: The RTS signal is capable of automatically controlling line
10   direction for the built-in half-duplex mode. The properties described
11   hereafter shall be given to a half-duplex capable UART node.

59     description: Output GPIO pin that sets the state of rs485-rx-during-tx. This
60       signal can be used to control the RX part of an RS485 transceiver. Thereby
61       the active state enables RX during TX.
