 * This program Demonstrates the operation of the power API lib
 *
 * The Hardware setup consists of a PIC32 pim on an Explorer16 board
 * The Explorer16 board is assumed to have a 8MHz crystal for POSC
 *
 * The device is placed in Sleep using the power save libray macro PowerSaveSleep()
 * The device is them woken by the WDT.
