EN_HIZ
R/W
0b
Device Hi-Z Mode Enable
When the charger is in Hi-Z mode, the device draws minimal quiescent
current. With VBUS above UVLO. REGN LDO stays on, and system
powers from battery.
0b: Device not in Hi-Z mode <default at POR>
1b: Device in Hi-Z mode

RESET_REG
R/W
0b
Reset Registers
All the registers go back to the default setting except the VINDPM register.
VSYS_MIN will always go back to 1S default setting (3.584V), and the
charging voltage goes back to the default values according to the cell pin
setting.
0b: Idle <default at POR>
1b: Reset all the registers to default values. After reset, this bit goes back
to 0.
When the battery voltage is lower than minimal system voltage, or the
battery is removed, it is NOT recommended to use this bit to reset the
registers to default values.

RESET_VINDPM
R/W
0b
Reset VINDPM Threshold
0b: Idle
1b: Converter is disabled to measure VINDPM threshold. After VINDPM
measurement is done, this bit goes back to 0 and converter starts.

EN_OTG
R/W
0b
OTG Mode Enable
Enable device in OTG mode when EN_OTG pin is HIGH.
0b: Disable OTG <default at POR>
1b: Enable OTG mode to supply VBUS from battery.

Enable ICO Algorithm
0b: Disable ICO algorithm. <default at POR>
