4.1.4  Data Analyzer 
The data analyzer mode allows you to view all bytes of data transferred on each port. 
Both the transmitted and received data bytes are displayed. Use of this feature is limited 
without a thorough understanding of the protocol. 
Important: When in analyzer mode, program execution will slow down. Only use 
this tool during a trouble-shooting session. Before disconnecting from the 
Config/Debug port, please be sure to press [M] to return to the main menu and 
disable the data analyzer. This action will allow the module to resume its normal 
operating mode.
