8.2. GPIO.1_ECI—RS-485 Transceiver Bus Control
GPIO.1_ECI is configurable as an RS-485 bus transceiver control pin or the Enhanced Communication Interface
which is connected to the DE and RE inputs of the transceiver. When configured for RS-485 mode, the pin is
asserted during UART data transmission as well as line break transmission and the RX Toggle mode is not
available. The RS-485 mode of GPIO.1_ECI is active-high by default, and is also configurable for active-low mode.
