THR bit can be let user to monitor the thermal regulation function is working or not.

0 : thermal Regulation is not working

1 : thermal Regulation is working

THR

Note : when PMU turn on, it would check the bit THR and compare to the value 0. If

it is different, INT would be asserted. After PMU is on, once THR bit toggles, INT

also asserts again.

Charger safety timer status.

0 : charger in charging or suspended by thermal loop

1 : safety timer expired

SAFE

Note : when PMU turn on, it would check the bit SAFE and compare to the value 0.

If it is different, INT would be asserted. After PMU is on, once SAFE bit toggles,

INT also asserts again.

CHG_2DET

The CHG_2DET bit is used to enable the secondary charger detection (to

distinguish CDP and DCP). Default value is 0. Set this bit value to 1 in order to

enable charger detection.

0 : Secondary CHARGER DETECTION DISABLED

1 : Secondary CHARGER DETECTION ENABLE.

CHG_1DET

The CHG_1DET bit is used to enable the primary charger detection. Default value

is 1 (auto-detect charger type when VIN plug in). Toggle this bit value (set to 0 and

then set 1) to re-enable charger detection.

0 : Primary CHARGER DETECTION DISABLED.

1 : Primary CHARGER DETECTION ENABLE.

CHGRUN

The CHGRUN bit is the charger detector status bit. It means the charger detection

is running or not.

0 : CHARGER DETECTION NOT RUNING.

1 : CHARGER DETECTION RUNNING.

Note : when PMU turn on, it would check the bit CHGRUN and compare to the

value 1. If it is different, INT would be asserted. After PMU is on, once CHGRUN

bit change from 1 to 0, INT also asserts again.
