The kit contains a board controller that is responsible for performing various board level tasks, such
as handling the debugger and the Advanced Energy Monitor. An interface is provided between the
EFM32 and the board controller in the form of a UART connection. The connection is enabled by setting
the EFM_BC_EN (PF7) line high, and using the lines EFM_BC_TX (PE0) and EFM_BC_RX (PE1) for
communicating.
Specific library functions has been provided in the kit Board Support Package that supports various
requests to be made to the board controller, such as quering AEM voltage or current. To use these
functions, the Board Support Package must be installed. See the Chapter 8 (p. 13) to find out more.
