5
Bus Mode
Selects the communication mode used to communicate with the
part in either 2-Wire or 3-Wire mode.

Internal Oscillator
If checked then the Daughter card crystal and on-chip oscillator
will be used to clock the Si4700/01/02/03. If the default is
unchecked, use the baseboard oscillator. Refer to Table 1, “EVB
Configuration Matrix,” on page 8 for important oscillator informa-
tion. Note that the on-chip oscillator is only available on revision B
silicon or later.
7
Auto Boot
If checked, the next time the GUI starts and only one EVB is
connected, the initialize screen will not appear and the part will be
booted automatically using the previous settings. This may be
changed by selecting FileInitialize and unchecking the box.

Initialize/Cancel Buttons
Press Initialize to activate the chip with the selected options
Press Cancel to exit.

Details Button
Not available with Si4700/01/02/03 parts.
6.1.2. 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.
