- step E2 the microcontroller CT in the device DI is awakened and takes control of the set DI and AP in order to install the configuration mode which will be selected.
- all the operations carried out in the following steps are controlled by the microcontroller CT directly or through the microcontroller C1 or one of the DSP processors C2 which then operates as a slave of the microcontroller CT.
- the AF display presents the list of configuration modes Ml to MQ recorded in the memory ME of the device DI, in the form of their names accompanied, where appropriate, by certain characteristics CAP.
- the user validates a selection of one of the configuration modes Mq displayed in particular by means of the keyboard CL so that the microcontroller Cl communicates an identifier of the mode selected to the microcontroller CT of the device DI, in step E4.
