Charge Time-out Interrupt Status. Set this bit with
TIMRPRE[ ] and/or TIMRTOT[ ] to 1 to generate an interrupt
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
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 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
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.

Temperature Status. Value is 0 when battery temperature is
outside of valid range. Value is 1 when battery temperature
is inside of valid range.
Input Voltage Status. Value is 1 when a valid input at
CHGIN is present. Value is 0 when a valid input at CHGIN
is not present.
Charge State Machine Status. Value is 1 indicates the
charger state machine is in EOC state, value is 0 indicates
the charger state machine is in other states.
CHGDAT1
Total Charge Time-out Interrupt control. Set both this bit and
TIMRSTAT[ ] to 1 to generate an interrupt when a total
charge time-out occurs. See the Charge Safety Timers
section for more information.
