//ConfigureIOPinsForLowPower();
//SaveStateOfAllInterruptEnableBits();
//DisableAllInterruptEnableBits();
//EnableOnlyTheInterruptsWhichWillBeUsedToWakeTheMicro(); //should enable at least USBActivityIF as a wake source
//Sleep();
//RestoreStateOfAllPreviouslySavedInterruptEnableBits(); //Preferrably, this should be done in the USBCBWakeFromSuspend() function instead.
//RestoreIOPinsToNormal(); //Preferrably, this should be done in the USBCBWakeFromSuspend() function instead.
//IMPORTANT NOTE: Do not clear the USBActivityIF (ACTVIF) bit here. This bit is
//cleared inside the usb_device.c file. Clearing USBActivityIF here will cause
//things to not work as intended.
