7 Board Controller

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.

Note

The board controller is only available when USB power is connected.
