    Note: Because the DO pin also goes high impedance, if the XTend RF Module is connected to a pro- cessor, the UART receive pin could be floating. A weak pull-up should be placed between the module and the microcontroller so that data is not interpreted as being transmitted to the microprocessor.      14 © 2007 MaxStream, Inc.
