This is the value of the VSR current step
as defined in the bq2014 data sheet.
This is the lower four bits of the TMPGG
register that correspond to the current
NAC value relative to either the LMD or
the original programmed full count (as
determined by PROG1-4). The GG step is
reported as a step number from 0 to 15,
with step 0 representing available capacity
from
0

representing
available capacity from 1516 full to full.
Indicates whether the present charge is
TRICKLE or FAST depending on the
state of the charge rate (CR) bit in
FLGS2.
This is the state of the EDV1 flag as pro-
grammed in the Display Program Menu.
The default is 1.05V. The EDV1 flag
latches ON if VSB drops below the EDV1

threshold value. It remains latched until
charging is detected, at which time it is
cleared.
This is the cell voltage at the SB pin of
the bq2014.
This multiplies the cell voltage by the
number of cells programmed in the Dis-
play Program Menu. The default is one
cell.
This is the state of the battery removed flag.
It is set (BRM = yes) if one of the conditions
indicating battery removed occurs. This
flag is reset when the battery is replaced.
This is the state of the VDQ bit in
FLGS1. VDQ = yes if the bq2014 is
charged until NAC = LMD. VDQ = no indi-
cates the present discharge is not valid for
LMD update.
