/* UART0
*
* 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.

/* LEDs
*
* The EFM32 Giant Gecko Start Kit has two yellow LEDs marked LED0 and LED1.
* These LEDs are controlled by GPIO pins on the EFM32. The LEDs are
* connected to pins PE2 and PE3 in an active high configuration:
*
* ------------------------------------- --------------------
* EFM32 PIN BOARD SIGNALS
* ------------------------------------- --------------------
* E2/BCK_VOUT/EBI_A09 #0/ MCU_PE2 UIF_LED0
* TIM3_CC2 #1/U1_TX #3/ACMP0_O #1
* E3/BCK_STAT/EBI_A10 #0/U1_RX #3/ MCU_PE3 UIF_LED1
* ACMP1_O #1
* ------------------------------------- --------------------
*
* All LEDs are grounded and so are illuminated by outputting a high
* value to the LED.
