h3lis200dl power-down mode

we are facing a problem to shut down h3lis200dl in our design. VDD is connected to VDD_IO and power is always connected to 3V battery (even when device is turned off). We are using SPI-communication and reading/setting registers works fine. It is just that I can't achieve anything near 1uAmp power down mode current consumption as stated by the datasheet even if setting PM0-PM2 to 0 (i.e. register 0x20 to 0x07) to power down the unit. The unit keeps consuming around 50uAmps.


Any ideas what might be missing here?
