4.2.2. Board Discovery Bus Mode
The initialize process can be configured to use either 2-wire or 3-wire bus mode. This can be configured by
selecting File Board Discovery Bus Mode.
This feature is useful when using the Silabs EVB and GUI to control a prototype that is designed to use one bus
mode only.
4.2.3. Function Configuration
For each mode available on the selected EVB, multiple configuration items (Figure 27) will be present to allow for
configuration of the GUI software. It is possible to change these settings to meet testing requirements. The default
configuration of the board when you connect it to the computer is acceptable for most users. After initialization, the
GUI will save and restore these settings whenever the same type of board is connected.

4.2.3.1. Functions
Currently the UI supports four possible functions. These functions are AM Receiver, FM Receiver, WB Receiver,
and FM Transmitter.
Each function is configured independently from other functions. It is important to configure all functions as desired
as it is possible to have FM Receive boot in digital mode while AM Receive boots in analog mode.
The currently highlighted function row will be the function that is initialized when the Initialize button is selected.
Settings for other functions that are not selected will be saved and used to initialize that function when choosing
another function from the UI main window.
4.2.3.2. Boot Mode
There are two boot modes possible for each function. It is possible for some boot modes to not be available on
some boards.
From Device—This option will use the firmware embedded on the device selected. This is the faster of the
two options.
From File—This option will use the patch functionality of the device to send firmware from a file stored
within the UI to the device. If using this option, choose the appropriate firmware in the Firmware column for
the function you are configuring.
