4.3 Backup Power Domain
The kit contains a backup capacitor that can be used together with the EFM32 Giant Gecko's backup
power domain. In this case, all other power sources are removed from the kit, and only a small part of
the EFM32 runs off the capacitor. It is also possible to enter backup mode while the Board Controller is
powered by selecting either BAT or USB with no battery in the socket or USB cable in the connector.
4.4 MCU Reset
The EFM32 MCU can be reset by a few different sources:
• The RESET button.
• The on-board debugger.
• An external debugger by pulling the #RST pin low.
4.5 Board Controller Reset
The Board Controller can be reset by removing and re-inserting the J-Link USB cable. Removing the
Board Controller USB cable will not reset the EFM32, but whenever the Board Controller is powered up
again, it will issue a RESET to the EFM32 through the on-board debugger.
