ADIS16364: Sensor overrange ?

Hi,

After writing the default (datasheet) value to the control registers of the IMU and performing a "precision autonull" (30s), I read the following control and status regs and obtain two strange values:

  :3FEC:87DB:0034:0000:0E00:0006:0001:0402:0000:0010

    :3FEC       product ID, OK

    :87DB       applied voltage, OK

    :0034        FLASH_CNT, OK

    :0000        ALM_CTRL, OK

    :0E00        GPIO_CTRL (default: 0x0000)    ***DIFFERS FROM DEFAULT VALUE***

    :0006        MSC_CTRL, OK

    :0001        SMPL_PRD, OK   

    :0402        SENS_AVG, OK

    :0000        SLP_CNT, OK

    :0010        DIAG_STAT   Status: ***SENSOR OVERRANGE***

What does this means?

I suppose the GPIO_CTRL value is a minor issue (since I don't need the GPIOs, only use DIO1 for "fresh data" signaling).

But the DIAG_STAT worries me, since the IMU is quiet.

SPI comm is working reliably.

BTW, there's a little errata in the datasheet (rev.D), at page 9 (backup to flash); where it says: "DIN = 0xBE04", it must be: "DIN = 0xBE08" .

TIA,

Sebastian.
