Interface doubts for ADIS16485

I am using ADIS16485 to monitor rate of my system. I am able to read gyro data. But some time I am getting spikes in gyro output. I have below doubts

  • From data sheet by default DIO2 will work as data ready pin. With present configuration I am not using it. Is it mandatory to use this pin ?
  • I have probed data ready pin and able to see pulses. Most of the time it is staying high. Periodically pin is falling low. What will happen if read data during this period ? Sensor is configured to operate in 32 sample /second.
  • After interfacing into system, I am unable to operate it low SPI clock (100 KHz). But it is working fine at high SPI clock (> 2 Mhz). What may be the reason ?
  • I am also reading some time data registers as zero including product ID. What may be the reason behind it.

Thanks & Regards
