LED and Pushbuttons
===================
LED
---
The LPC4357-EVB has one user-controllable LED labelled D6 controlled
by the signal LED_3V3:
LED SIGNAL MCU
D6 LED_3V3 PE_& GPIO7[7]
LED is grounded and a high output illuminates the LED.
If CONFIG_ARCH_LEDS is defined, the LED will be controlled as follows
for NuttX debug functionality (where NC means "No Change").
-------------------------- ---------
LED
-------------------------- ---------
LED_STARTED OFF
LED_HEAPALLOCATE OFF
LED_IRQSENABLED OFF
LED_STACKCREATED ON
LED_INIRQ NC
LED_SIGNAL NC
LED_ASSERTION NC
LED_PANIC Flashing
-------------------------- ---------
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);
Pushbuttons

1. This configuration derives from the LPC4330 Xplorer configuration. In
many cases there have been global substitutions for naming to the
LPC4357 EVB without corresponding updates to the technical description.
Thus all technical details should be taken with a grain of salt. Things
like LEDs and buttons actually are remnants of the LPC4330-Xplorer that
still need clean-up.
Thus all technical details should be taken with a grain of salt. GPIO
definitions may actually are remnants of the LPC4330-Xplorer that still
