Dear all,
My bq40z50 EVM as received from TI has the Operation Status Reg A set to 0x6181 which is Unsealed mode. I want to change this to Full Access.
I have tried to follow the TRM 10.5.3 page 66 and 12.1.33 page 75 writing the two Words 0XFFFF and 0XFFFF within 4 Seconds from Manufacturer Access (register top left of Battery Management Studio) but With no sucess. After a lot of trials I still read 0x6181
I am pretty sure I am doing something wrong and after a lot of trials I rather ask the Forum for help
Any comments from those who knows how to do ut will be much apprciated
Best regards
Kjell
