Output Discharge Control. When activated, LDO output is
discharged to GA through 1.5kꢀ resistor when in shutdown.
Set bit to 1 to enable output voltage discharge in shutdown,
clear bit to 0 to disable this function.
DIS
LDO Low-IQ Mode Control. Set bit to 1 for low-power
operating mode, clear bit to 0 for normal mode.

R/W when charge safety timers expire, read this bit to get charge
time-out interrupt status. See the Charge Safety Timers
section for more information.
Battery Temperature Interrupt Status. Set this bit with
TEMPIN[ ] and/or TEMPOUT[ ] to 1 to generate an interrupt
R/W when a battery temperature event occurs, read this bit to get
the battery temperature interrupt status. See the Battery
Temperature Monitoring section for more information.
Input Voltage Interrupt Status. Set this bit with INCON[ ] and/or
INDIS[ ] to generate an interrupt when UVLO or OVP condition
R/W occurs, read this bit to get the input voltage interrupt status.
See the Charge Current Programming section for more
information.
Charge State Interrupt Status. Set this bit with
CHGEOCIN[ ] and/or CHGEOCOUT[ ] to 1 to generate an
R/W interrupt when the state machine gets in or out of EOC state,
read this bit to get the charger state interrupt status. See the
State Machine Interrupts section for more information.
