/* LED definitions **********************************************************/
/* The LPC4330-Xplorer has 2 user-controllable LEDs labeled D2 an D3 in the
* schematic and on but referred to has LED1 and LED2 here, respectively.
*
* LED1 D2 GPIO1[12]
* LED2 D3 GPIO1[11]
*
* LEDs are pulled high to a low output illuminates the LED.
*
* If CONFIG_ARCH_LEDS is defined, the LEDs will be controlled as follows
* for NuttX debug functionality (where NC means "No Change").
*
* ON OFF
* LED1 LED2 LED1 LED2
* LED_STARTED 0 OFF OFF - -
* LED_HEAPALLOCATE 1 ON OFF - -
* LED_IRQSENABLED 1 ON OFF - -
* LED_STACKCREATED 1 ON OFF - -
* LED_INIRQ 2 NC ON NC OFF
* LED_SIGNAL 2 NC ON NC OFF
* LED_ASSERTION 2 NC ON NC OFF
* LED_PANIC 2 NC ON NC OFF
*
* If CONFIG_ARCH_LEDS is not defined, then the LEDs are completely under
* control of the application. The following interfaces are then available
* for application control of the LEDs:
*
* void lpc43_ledinit(void);
* void lpc43_setled(int led, bool ledon);
* void lpc43_setleds(uint8_t ledset);
