* - SLEEPMODE_IDLE
* Only the CPU is idled. The rest of the chip continues runing
* normally. The chip will wake from any interrupt.
* - SLEEPMODE_WAKETIMER
* The sleep timer clock sources remain running. The RC is always
* running and the 32kHz XTAL depends on the board header. Wakeup
* is possible from both GPIO and the sleep timer. System time
* is maintained. The sleep timer is assumed to be configured
* properly for wake events.
* - SLEEPMODE_MAINTAINTIMER
* The sleep timer clock sources remain running. The RC is always
* running and the 32kHz XTAL depends on the board header. Wakeup
* is possible from only GPIO. System time is maintained.
* - SLEEPMODE_NOTIMER
* The sleep timer clock sources (both RC and XTAL) are turned off.
* Wakeup is possible from only GPIO. System time is lost.
