SLLU131B – July 2010 – Revised February 2011
GPIOs/LEDs/PBUTTON
1
GPIO LEDs
Each GPIO is connected to an LED on the DEMO Board. The LEDs are located along the top side of the
board (D1 – D8). The LEDs are for test purposes and can be used to indicate device operational states.
This is firmware dependent.
2
PWM LEDs
Each PWM is connected to an LED (D3 and D6) on the DEMO Board. PWM LEDs are for test purposes
and can be used to indicate hard drive activity or USB activity. This is firmware dependent.
3
GPIO Push Button
There is one GPIO configurable push button (SW1) on the DEMO Board. This push button is connected to
GPIO3. This is firmware dependent.
