BQ40Z80EVM-020: the expected output is not getting as a response for the command

Hello Sir ,

i am testing 0x0051 command as per the manufacture access , and i am expecting the response with the 0x0051 command.

but all time we dont get the response from BQ40z80 with 0x0051 , we get the response with 0x0054 response for even we trying 0x0051 /0x0006 command .

Let me know what was the reason.

For the below screenshot we are trying to send 0x0006 command for reading chemid , but we didnt get the response  with the same id , we are getting response from 54 00 01 69 00 00 , let me know why it  is happening.
