/* If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in
* any way. The following definitions are used to access individual LEDs.
*
* LED1 -- Connected to P1[14]
* LED2 -- Connected to P0[16]
* LED3 -- Connected to P1[13]
* LED4 -- Connected to P4[27]
*
* These LEDs are connected to ground so a high output value will illuminate
* them.
*
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the two LEDs
* on the LPC4088 Developer's Kit. The following definitions describe how
* NuttX controls the LEDs:
*
* LED1 LED2 LED3 LED4
* LED_STARTED 0 OFF OFF OFF OFF
* LED_HEAPALLOCATE 1 ON OFF OFF OFF
* LED_IRQSENABLED 2 OFF ON OFF OFF
* LED_STACKCREATED 3 ON ON OFF OFF
* LED_INIRQ 4 LED3 glows, on while in interrupt
* LED_SIGNAL 4 LED3 glows, on while in signal handler
* LED_ASSERTION 4 LED3 glows, on while in assertion
* LED_PANIC 4 LED3 Flashes at 2Hz
* LED_IDLE 5 LED glows, ON while sleeping
