Working mode selection

The L3G4IS can be used for user interface and image stabilization applications. Depending

on the power supply provided and dedicated internal bits configuration, the L3G4IS is able

to keep both reading chains active allowing the user to exploit the advantages of high

resolution on low full-scale and low current consumption on high full-scale at the same time

through SPI and I2C digital interfaces.

When either AVdd or HAVdd are removed they must be connected to GND for proper

working of the device.
