7.8 Configuration Tasks and Codes
The device executes Configuration Tasks while in configuration mode. (See section 7.4.2 for a description
of device operating modes and how to change between them, and User Manual section 9.19 for more
details on a particular task). These tasks and their data are used to configure device subsystems.
Data required for the Configuration Task is loaded into the device using a Data Task, which can be
executed at the same time as the Configuration Task if it requires less than four words.
