* 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.
