+/* 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

+ *   ACMP1_O #1
+ * ------------------------------------- --------------------
+ *
+ * All LEDs are grounded and so are illuminated by outputting a high
+ * value to the LED.
