Spi read response incorrect

Category: Hardware
Product Number: ADXL373

Hi,

I am trying to read the ADXL373 data, however I think the response I am receiving is incorrect.

Below is the data that I receive when I access the device registers:

Register

Register Data Read
0x00 0xF9
0x00 0x19
0x02 0xFF
0x03 0xF8

This is not the expected values for these registers.

Also, I think the write operation is working because when I write 0x81 to the interrupt register 0x3B to enable active low interrupt on INT1 I see that the device starts generating data ready interrupt.

I was also able to change the mode from standby to Full bandwidth measurement mode in the Power_ctl register 0x3F.
