Extreme Low Power

Multiple Power Management Options for Extreme Power Reduction:
VBAT allows for lowest power consumption on backup battery (with or without RTCC)
Deep Sleep allows near total power-down with the ability to wake-up on external triggers
Sleep and Idle modes selectively shut down peripherals and/or core for substantial power reduction and fast wake-up
Doze mode allows CPU to run at a lower clock speed than peripherals
Alternate Clock modes allow On-the-Fly Switching to a Lower Clock Speed for Selective Power Reduction
