[4:3] VTRK_DEAD[1:0] R/W 01 = 2.5 V Trickle to fast charge dead battery voltage programming bus. The
values of the trickle to fast charge threshold can be programmed to
the following values:
00 = 2.0 V.
01 = 2.5 V.
10 = 2.6 V.
11 = 2.9 V.
[2:0] VWEAK[2:0] R/W 011 = 3.0 V Weak battery voltage rising threshold.
000 = 2.7 V.
001 = 2.8 V.
010 = 2.9 V.
011 = 3.0 V.
100 = 3.1 V.
101 = 3.2 V.
110 = 3.3 V.
111 = 3.4 V.

3 DIS_LDO R/W 0 0 = LDO is enabled.
1 = LDO is off. In addition, if EN_CHG = low, the battery isolation
FET is on. If EN_CHG = high, the battery isolation FET is off.
