ADXL362 No Data received

I am struggling to get any response from this device.

 

I am trying to read from register 0x00.

 

attached is the scope output from my clock and MOSI lines.

 

There are three bytes sent - 0x0B for read, 0x00 for the first register, and 0x00 to clock data in.

 

MISO never goes high. sometimes it shows a slight amount of noise that resembles the MOSI line but I am talking a couple of mVolts.

 

I have tried 150ohm resistors in line on all SPI lines.

 

Am I running too slow?

 

CS is permanently low as I am only talking to this device.

 

Can anyone see anything wrong with the timing? all voltages are around 3V.

 

please Help!!!!

 

Thanks
