Hibernation Module
The Hibernation Module requires special system implementation considerations since it is intended
to power-down all other sections of its host device. The system power-supply distribution and
interfaces to the device must be driven to 0 V_DC or powered down with the same external voltage
regulator controlled by HIB.
The external voltage regulators controlled by HIB must have a settling time of 250 μs or less.
