/* There are two LEDs on the SAMA5D3 series-CM board that can be controlled
|
|
* by software. A blue LED is controlled via PIO pins. A red LED normally
|
|
* provides an indication that power is supplied to the board but can also
|
|
* be controlled via software.
|
|
*
|
|
* PE25. This blue LED is pulled high and is illuminated by pulling PE25
|
|
* low.
|
|
*
|
|
* PE24. The red LED is also pulled high but is driven by a transistor so
|
|
* that it is illuminated when power is applied even if PE24 is not
|
|
* configured as an output. If PE24 is configured as an output, then the
|
|
* LCD is illuminated by a low output.
