DRV8323R: SPI DEBUG:Register status display is incomplete

Part Number: DRV8323R
Other Parts Discussed in Thread: DRV8323

Tool/software:

Hi,

I am currently learning how to use the SPI communication of the DRV8323RS, but I have encountered a problem.I sent the instruction to read the registers of DRV8323 using the host, and also received the data sent back by DRV8323. However, the received data was incomplete.Specifically, the register status of DRV8323 is a 11-bit data. I can only receive 8 bits (0-7).For instance, when I sent the data 0xB000 to DRV8323, this was a command to read the CSA Control register. According to the logic, the expected response should have been 0x0283. But I could only receive 0x0083. The last three digits were lost.

I would like to know if this phenomenon is normal? If everything is normal, then how can I view the complete register status? If my observation is incorrect, please let me know where the problem might lie.

Best wishes,

huan yin
