LSM330DL - DataRready Interrupt

Hi community,
i am working on an application with the accelerometer and gyroscope in LSM330DL.
At the moment I try to use the DataReady-Interrupt for the gyroscope.
My understanding of DRDY-Interrupt is that whenever new data is stored in the register, the sensor pull down the DRDY-Pipe.
I have tryed several configurations, hardware adjustments and so on but nothing works properly.
The DRDY-Pipe is always in high-state.

At the moment i have a very basic test program, where i initialize the sensor and wait for an interrupt.
In the following my configuration of the gyroscope:
REG1: 400Hz - 50Hz cutoff, normal mode, xyz - enable
REG2: everything 0
REG3: I2_DRDY enable
REG4: continuous update, LSB, 2000dps, 4-wire
REG5: FIFO disabled, HPF disabled

I asked the same question more than one week ago to the st-support, but no one answered me.

I hope you can help me!

Best Regards,
Patrick
