EIC Example1 for EVK1100 Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the EIC driver. This documentation is also bundled with an example.

This example shows how to use an external interrupt to wake up the cpu when in sleep mode (static).
Operating mode:

1. At the beginning, the CPU is set in the Static sleep mode.
2. To leave the sleep mode, the user needs :
   • Press the Joystick on EVK1100
   • Press the pushbutton PB0 on EVK1101
   • Set PA20 low on EVK1104
   • Set PA29 low (press button PB1) on UC3C_EK
   • Set PA09 low on AT32UC3L-EK.
   • Press SWITCHES.SW0 (setup can be found in conf_example1) In normal mode (i.e. out of the sleep mode), the led LED0 toggles for a short while; the CPU is then switched back again into the Static sleep mode (back to step 1)...etc
