-
When low level is inputted, module enters configuration
mode; when high level is inputted, module enters
transparent transmission mode (it contains internal pull-up
resistance and operates in transparent transmission mode
by default)

To indicate data outputted via serial port is valid, and the
low level indicates that data is in transmission and the high
level indicates that data transmission has completed (see
more details on <2.5 Data validity >)
Module outputs serial port data
Module receives external serial port data
