After the start-up the angular rate and acceleration data is immediately available through SPI
registers. There is no need to initialize the gyroscope or accelerometer before starting to use it. If
the application requires monitoring operation correctness there are several options available to
monitor the status.
To ensure correct ASIC start up please connect the digital supply voltage V
analog supply voltage V
twice to clear error flags. Angular rate data is available immediately so no start up command
sequence is required if error flags are not used.
For correct device operation there are no specific configuration needed for the device before
starting of measuring the acceleration. However if the device diagnostic features are being used
the following operations could be made after the powering on the device.
