8 Board controller
The control MCU can act as a board controller (BC). There is a UART connection between the EFM and
the BC. The connection is made by setting the bc_en line high. The EFM can then use the BSP to send
commands to the BC. When bc_en is low, bc_tx and bc_rx can be used by other applications.
To use the board controller for your application, the Board Support Package (BSP) must be installed.
See the BSP chapter to find out how.
Note
The board controller is only available when the STK is powered by USB.
