Hi Sir ,
Our design a battery pack , use the BQ20z655-R1 and 2P4S 18650 cell construction .
we read Ra value from some battery packs ,
some samples Cell0 R_a flag, Cell1 R_a flag, Cell2 R_a flag, Cell3 R_a flag value are 0055 , xCell0 R_a flag, xCell1 R_a flag, xCell2 R_a flag, xCell3 R_a flag value are FFFF .
some samples Cell0 R_a flag, Cell1 R_a flag, Cell2 R_a flag, Cell3 R_a flag value are 0555 , xCell0 R_a flag, xCell1 R_a flag, xCell2 R_a flag, xCell3 R_a flag value are FFFF.
some samples Cell0 R_a flag, Cell1 R_a flag, Cell2 R_a flag, Cell3 R_a flag value are 0055 , xCell0 R_a flag, xCell1 R_a flag, xCell2 R_a flag, xCell3 R_a flag value are 0000.
Which one is right?
What are the correct value of Cell0 R_a flag, Cell1 R_a flag, Cell2 R_a flag, Cell3 R_a flag?
What are the correct value of xCell0 R_a flag, xCell1 R_a flag, xCell2 R_a flag, xCell3 R_a flag?
Clould you help to check our Ra table value ? thanks very much.
Thanks!

Hi aiming,
The values in both tables are correct. The ra table updates switch between ra and rax tables so that we are not wearing out the memory location quickly by writing to the same place. In this case, the last ra updates are done to the table with ra flag set to 0000.
