Power-on and Power-off Sequence

Power-on sequence

Turn On the power supplies so that the power supplies rise in order of 1.1 V power supply (DVDD) →1.8 V power

supply (OVDD) → 2.9 V power supply (AVDD). In addition, all power supplies should finish rising within 200 ms.

The register values are undefined immediately after power-on, so the system must be cleared. Hold XCLR at Low

level for 500 ns or more after all the power supplies have finished rising. (The register values after a system clear

are the default values.)

The system clear is applied by setting XCLR to High level. The maser clock input after setting the XCLR pin to High

level.

Make the sensor setting by register communication after the system clear.
