((7*2) + 16)/10
Maximum charge temperature is 74 - (mt x 1.6)°C
(mt = upper nibble). The
T step is (dT*2+16)/10°C
(dT = lower nibble).

This packed field is the two's complement of
52.73/x, where x = %/day is the self-discharge rate
desired at room temperature.
This field is used to set the digital magnitude filter
as described in Table 2.
This field represents the following: 3.2/sense resis-
tor in ohms. It is used by the bq2092 to scale the
measured voltage values on the SR pin in mA and
mAh. This register also compensates for variations
in the reported sense resistor value.
This packed field is the two’s complement of the
desired value in RM when the bq2092 determines
a full charge termination. If RM is below this
value, RM is set to this value. If RM is above this
value, then RM is not adjusted.
This packed value is used to set the fast charge and
maintenance charge efficiency for nickel-based batter-
ies. The upper nibble adjusts the maintenance charge
compensation; the lower nibble adjusts the fast
charge compensation.
Maintenance, upper nibble = (eff%
256 - 128)/8
Fast charge, lower nibble = (eff%
256 - 192)/4
