RCXN_CELL11_

BKUP,

0x03D4

These bits are the backup register for

cell 11’s

connection resistance state. This address is a

R/W alias for the RCXN_CELL11 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 backup register or any other

cell RCXN register prepares the fuel gauge to

use the values written in this register as a

starting point for the RCXN learning.
