Bit Description

power_off_at_vsuplow

Switch ON Power OFF mode if low VSUP is detected

during active or standby mode (Pin ON= low and

bit auto_off=0)

0 : If low battery is detected, continuously monitor

battery voltage and startup if battery voltage is

above ResVoltrise

1 : If low battery is detected, enter power OFF mode

6ovprot_dis

Enables external overvoltage protection, function

of xoff

0 : Overvoltage protection disabled

1 : Overvoltage protection enabled

5on_reset_delay

Sets the ONKEY/ENx long press delay time

0 : 8 sec

1 : 4 sec if onkey_lpress_reset=0; ONKEY/ENx long

press is disabled if onkey_lpress_reset=1

onkey_lpress_reset

Selects behavior for ONKEY/ENx long press

0 : Change to power_off mode

1 : Reset cycle started if on_reset_delay=0;

ONKEY/ENx long press is disabled if

on_reset_delay=1

dcdc_chmode

Selects between linear and step down charger

0 : Linear charger enabled

1 : Step down charger enabled

2SupResEn

0 : A reset is generated if VSUP falls below 2.7V.(1)

1 : A reset is generated if VSUP falls below

ResVoltFall

1gpio12_in_en

Enables input_pulldown for gpio1,gpio2 if this bit is

set

0 : gpio1_mode and gpio2_mode are default (b011)

1 : gpio1_mode and gpio2_mode set to (b101)

input with pulldown

dis_bypass

Used in charger FSM
