BQ76952: Turn on the CRC function the device has no responds

Hello Sir:

We turn on the CRC function and try to write the sub command or command.

But the read data is not correct that device looks doesn't write data. 

Please refer the figure as below.

Step 1 write sub command

Step 2 write command

Step 3 read sub command

Step 4 read command

If we turn off the CRC and the data will be ok.

Please refer the attached file CRC8_OFF.

Please provide the recommendations for us and let us know which points we need to pay attention.

Thanks a lot.CRC8_OFF.zip
