If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
the Freedom K28. Usage of these LEDs is defined in include/board.h and
src/k28_leds.c. The following definitions describe how NuttX controls the
LEDs:

LED_SIGNAL In a signal handler (no change)

LED_IDLE K28 is in sleep mode (Optional, not used)
Buttons
-------
Two push button switches, SW2 and SW3, are available on the FRDM-K28F
board. SW2 is connected to PTA4 and SW3 is connected to PTD0.
Beside the general purpose IO function, both SW2 and SW3 can be used
as a low-leakage wakeup (LLWU) source.
