TIMRSTAT
R/W
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.
APCH
0x78
[6]
TEMPSTAT
R/W
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.
APCH
0x78
[5]
INSTAT
R/W
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.
APCH
0x78
[4]
CHGSTAT
R/W
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.
APCH
0x78
[3]
TIMRDAT
R
