Question

What is the behavior of the CP210x in RS485 mode when sending a line break?  How does the transceiver enable pin behave?

Answer

When GPIO.2 is configured for alternate function (RS-485 transceiver enable), the pin is activated when either data or a line break is transmitted.   It cannot be configured to enable only on data transmission, or only on line break.
