/* UART0
*
* The control MCU acts as a board controller (BC). There is a UART
* connection between the EFM and the BC. The connection is made by
* setting the EFM_BC_EN (PD13) line high. The EFM can then use the BSP to
* send commands to the BC. When EFM_BC_EN is low, EFM_BC_TX and EFM_BC_RX
* can be used by other applications.

/* LEDs
*
* The EFM32 Gecko Start Kit has four yellow LEDs. These LEDs are connected
* as follows:

* ------------------------------------- --------------------
* EFM32 PIN BOARD SIGNALS
* ------------------------------------- --------------------
* C0/USART1_TX#0/PCNT0_S0IN#2/ACMP0_CH0 MCU_PC0 UIF_LED0

* C3/USART2_RX#0/ACMP0_CH3 MCU_PC3 UIF_LED3
* ------------------------------------- --------------------
*
* All LEDs are grounded and so are illuminated by outputting a high
* value to the LED.
