*
* Revision Description
* ======== ===========
* 1.30 Added support for ATMega168, ATMega2560, ATMega1280 & ATMega32U4.
* Tested to work with Arduino IDE 1.0.1 - 1.0.4.
* 1.20 Remove typo error in idle method for checking whether Timer 0 was
* turned off.
* Remove dependecy on WProgram.h which is not required.
* Tested to work with Arduino IDE 1.0.
* 1.10 Added #ifndef for sleep_bod_disable() for compatibility with future
* Arduino IDE release.
* 1.00 Initial public release.

* asynchronous clock source to Timer 2. Please take note that
* Timer 2 is also used by the Arduino core for PWM operation.
* Please refer to wiring.c for explanation. Removal of the external
* 8/16 MHz crystal/resonator requires the microcontroller to run
* on its internal RC oscillator which is not so accurate for time
* critical operation.
*
* Argument Description
* ========= ===========
* 1. period Duration of low power mode. Use SLEEP_FOREVER to use other wake
* up resource:
* (a) SLEEP_15MS - 15 ms sleep
* (b) SLEEP_30MS - 30 ms sleep
* (c) SLEEP_60MS - 60 ms sleep
* (d) SLEEP_120MS - 120 ms sleep
* (e) SLEEP_250MS - 250 ms sleep
* (f) SLEEP_500MS - 500 ms sleep
* (g) SLEEP_1S - 1 s sleep
* (h) SLEEP_2S - 2 s sleep
* (i) SLEEP_4S - 4 s sleep
* (j) SLEEP_8S - 8 s sleep
* (k) SLEEP_FOREVER - Sleep without waking up through WDT
*
* 2. adc ADC module disable control. Turning off the ADC module is
* basically removing the purpose of this low power mode.
* (a) ADC_OFF - Turn off ADC module
* (b) ADC_ON - Leave ADC module in its default state
*
* 3. bod Brown Out Detector (BOD) module disable control:
* (a) BOD_OFF - Turn off BOD module
* (b) BOD_ON - Leave BOD module in its default state
*
* 4. timer2 Timer 2 module disable control:
* (a) TIMER2_OFF - Turn off Timer 2 module
* (b) TIMER2_ON - Leave Timer 2 module in its default state

* 1.30 Added support for ATMega168, ATMega2560, ATMega1280 & ATMega32U4.
* Tested to work with Arduino IDE 1.0.1 - 1.0.4.
* 1.20 Remove typo error in idle method for checking whether Timer 0 was
* turned off.
* Remove dependecy on WProgram.h which is not required.
* Tested to work with Arduino IDE 1.0.
* 1.10 Added #ifndef for sleep_bod_disable() for compatibility with future
* Arduino IDE release.
