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.
INDAT
R
R
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.
CHGDAT
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.

Battery Temperature Interrupt Control. Set both this bit and
TEMPSTAT[ ] to 1 to generate an interrupt when the battery
temperature goes into the valid range. See the Battery
Temperature Monitoring section for more information.
Input Voltage Interrupt Control. Set both this bit and
INSTAT[ ] to 1 to generate an interrupt when CHGIN input
voltage goes into the valid range. See the Charge Current
Programming section for more information.
INCON
Charge State Interrupt Control. Set both this bit and
CHGSTAT[ ] to 1 to generate an interrupt when the state
machine goes into the EOC state. See the State Machine
Interrupts section for more information.

PRECHARGE Time-out Interrupt Control. Set both this bit
and TIMRSTAT[ ] to 1 to generate an interrupt when a
PRECHARGE time-out occurs. See the Charge Safety
Timers section for more information.
Battery Temperature Interrupt Control. Set both this bit and
TEMPSTAT[ ] to 1 to generate an interrupt when the battery
temperature goes out of the valid range. See the Battery
Temperature Monitoring section for more information.
Input Voltage Interrupt Control. Set both this bit and
INSTAT[ ] to 1 to generate an interrupt when CHGIN input
voltage goes out of the valid range. See the Charge Current
Programming section for more information.
Charge State Interrupt Control. Set both this bit and
CHGSTAT[ ] to 1 to generate an interrupt when the state
machines jumps out of the EOC state. See the State
Machine Interrupts section for more information.

Reserved.
ACIN Status. Indicates the state of the ACIN input, typically
in order to identify the type of input supply connected. Value
is 1 when ACIN is above the 1.2V precision threshold, value
is 0 when ACIN is below this threshold.
