Bit 7..5 CH_VLTG2..CH_VLTG0 (charge voltage selection):
000 = 4.15V
001 = 4.175V
010 = 4.20V
011 = 4.225V
100 = 4.25V
101 = 4.275V
110 = 4.30V
111 = 4.325V
Bit 4..3 TMP_SHIFT1..TMP_SHIFT0 (battery temperature shift):
00 = the temperature for TS_COLD and TS_HOT is at 0°C/45°C
01 = the temperature window is shifted by 5°C to TS_COLD/TS_HOT = 5°C/50°C
10 = the temperature window is shifted by 10°C to TS_COLD/TS_HOT = 10°C/55°C
11 = the temperature window is shifted by 15°C to TS_COLD/TS_HOT = 15°C/60°C
Bit 2..1 VBAT1..VBAT0 (battery voltage comparator threshold; for Li primary cells):
00 = 2.2V
01 = 2.3V
10 = 2.4V
11 = 2.5V
Bit 0 VBAT_COMP (battery voltage comparator output):
0 = voltage above the threshold
1 = voltage below the threshold or comparator disabled
