Hi Team,

My customer want to setting sealed mode for BQ76942, and would like to set below unseal key and full access key. But we can't understand below step3 and step4 which mentioned in technical manual, could you possible help to use customer key as an example to show how to get the checksum value and the length of 0x0A? Thanks a lot for your help.

Best regards

Jie
