BQ76PL455A-Q1: My system show "USER_CKSUM_ERR" fault

Part Number: BQ76PL455A-Q1
Other Parts Discussed in Thread: BQ76PL455-Q1

Hi Ti,

My platform is bq76pl455-Q1 and  I tested the register of FAULT_SUM(0x52-0x53) function. The system show of  "CHIP_FAULT_SUM" is faulted. Because of  FAULT_DEV[USER_CKSUM_ERR] is setting.

Base on spec.(SLUSC51C –APRIL 2015–REVISED NOVEMBER 2016),  It said "...When CSUM and CSUM_RSLT do not match, the FAULT_DEV[USER_CKSUM_ERR] flag will be set until the condition is corrected."

So, what can I do to clear this fault ? May I need write CSUM_RSLT value back to the CSUM register ?
