mfiore 0:86bd3121e22f 2 *
mfiore 0:86bd3121e22f 3 * This program demonstrates how to handle external interrupts using the
mfiore 1:ae672188eeb7 4 * MultiTech mDot and MultiTech UDK2 hardware. The only
mfiore 0:86bd3121e22f 5 * additional hardware required is a jumper wire.
mfiore 0:86bd3121e22f 6 *
mfiore 0:86bd3121e22f 7 * Pins are active low, so 0V = 0 and 5V/3.3V = 1.
mfiore 0:86bd3121e22f 8 *
mfiore 0:86bd3121e22f 9 * This program configures interrupt handlers for rising and falling edges
mfiore 1:ae672188eeb7 10 * on pin XBEE_AD3 (UDK2 pin D10).
