IAICR[1:0]

When IAICR_SEL = 0

00 : VIN 100mA current limit, 01 : VIN 500mA current limit,

10 : VIN 1A current limit, 11 : no input current limit (default 01)

When IAICR_SEL = 1

00 : VIN 100mA current limit, 01 : VIN 700mA current limit,

10 : VIN 700mA current limit, 11 : no input current limit (default 01)

TE_SHDN_EN

0 : When EOC is triggered, charge is not shutdown

1 : When EOC is triggered, charge is shutdown

TE

1 : Enable end of charge detection, 0 : Disable end of charge detection (default 0)

IAICR_INT

IAICR setting bit

0 : decided by external OTG pin, 500mA current limit when OTG pin is low and 100mA

current limit when OTG pin is high

HZ

1 : High impedance mode, 0 : Not high impedance mode (default 0)

OPA_MODE

1 : Boost mode, 0 : Charger mode (default 0)
