[5:4]

TOTTIMO

R/W

Total Charge Time-out Selection. See the Charge Safety

Timers

section for more information.

APCH

0x71

[3:2]

PRETIMO

R/W

Precondition Charge Time-out Selection. See the Charge

Safety Timers

section for more information.

APCH

[1:0]

OVPSET

R/W

Input Over-Voltage Protection Threshold Selection. See the

Input Over-Voltage Protection

section for more information.

APCH

0x78

[7]

TIMRSTAT1

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]

TEMPSTAT1

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]

CHGSTAT1

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]

TIMRDAT1

Charge Timer Status. Value is 1 when precondition time-out

or total charge time-out occurs. Value is 0 in other case.

APCH

0x78

[2]

TEMPDAT1

Temperature Status. Value is 0 when battery temperature is

outside of valid range. Value is 1 when battery temperature

is inside of valid range.

APCH

0x78

[1]

INDAT

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.

APCH

0x78

[0]

CHGDAT1

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.

APCH

0x79

[7]

TIMRTOT

R/W

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.

APCH

0x79

[6]

TEMPIN

R/W

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.

APCH

0x79

[5]

INCON

R/W

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.

: Valid only when CHGIN UVLO Threshold<VCHGIN<CHGIN OVP Threshold.
