In normal operation mode, the sensor transmits sensor output data in data range 1. A

special “diagnostic mode” is foreseen for testing and failure analysis. In the diagnostic

mode, the sensor may send other than the specified sensor output data in data range 1. The

condition for entering the diagnostic mode is the recognition of a valid “XLong” data frame

during initialization phase II. The sensor indicates the diagnostic mode by sending the

“Sensor in diagnostic mode” identifier during initialization phase III, see Section 2.4.3.

Absolute maximum ratings

Stresses above those listed as absolute maximum ratings may cause permanent damage to

the device. This is a stress rating only and functional operation of the device under these

conditions is not implied. Exposure to maximum rating conditions for extended periods may

affect device reliability.

This device is sensitive to mechanical shock, improper handling can cause

permanent damage to the part

This device is sensitive to electrostatic discharge (ESD), improper handling can

cause permanent damage to the part

2.6

Factory calibration

The IC interface is factory calibrated for sensitivity (So) and Zero-g level (Off).

The trimming values are stored inside the device in a non-volatile structure. Any time the

device is turned on, the trimming parameters are downloaded into the registers to be

employed during normal operation. This allows the user to employ the device without further

calibration.
