4.5 Idle Mode
The 3D MagIC incorporates an Idle Mode to reduce power consumption, in which the circuit
automatically idles when it is not exchanging data or taking a measurement. The 3D MagIC
starts in the Idle Mode at power-up and remains in Idle Mode until a measurement is needed.
Note: The 3D MagIC starts in Idle Mode when powered on. This is different from the legacy 11096
ASIC, which required cycling through one measurement request operation to put it into Idle Mode.
