RESR_CELL_

DIS_9_BKUP,

0x0220

These bits are the backup register for cell

9’s

discharge RESR state. This address is a R/W

alias for the RESR_CELL_DIS_9 register.

The fuel gauge must be in learning backup mode

for this register to be written. For more details, see

the FG_BKUP_ENABLE register on page 33 and

the FG_BKUP_FLAG register on page 54.

Writing to this or any of the other cell RESR

backup registers prepares the fuel gauge to use

the values written in these registers as a starting

point for the RESR learning.
