8. XBee Analog and Digital I/O Lines
XBee ZB firmware supports a number of analog and digital I/O pins that are configured through software commands.
Analog and digital I/O lines can be set or queried. The following table lists the configurable I/O pins and the
corresponding configuration commands.

I/O Configuration
To enable an analog or digital I/O function on one or more XBee module pin(s), the appropriate configuration
command must be issued with the correct parameter. After issuing the configuration command, changes must be
applied on the module for the I/O settings to take effect.
