+		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.
