Previous topics have nothing to do with this topic. You did not provide BatInfo and Reset tab snapshots. Support could not be provided due to missing information. 

Another thing that you improvising on your own and send non relevant command to the chip.

write word 0021 to register 00,

we never recommend this for bq40320, you found it in bq20zXXX tutorial which has nothing to do with bq40320. These are different chips.
