Battery Charger Enable
0 = Disable
1 = Enable
Protected by security key.
Force charging
0 = Normal behaviour
1 = Force charging
CHG_FRC enables charging even if the battery voltage
is above the restart threshold.
It is not recommended to use this feature; there are
safety implications in its use.
This bit should be reset to 0 after charging has started.
Host processor should monitor CHG_MODE_EINT to
confirm that charging has started.
Protected by security key.
Battery End of Charge current threshold
000 = 20mA
001 = 30mA
010 = 40mA
011 = 50mA
100 = 60mA
101 = 70mA
110 = 80mA
111 = 90mA
Protected by security key.
Battery Fast Charge Enable
0 = Disable
1 = Enable
Protected by security key.
Enable battery charge current monitor at AUXADCIN1.
0 = Disabled
1 = Enabled
(Note - a resistor is required between AUXADCIN1 and
GND in order to measure the charge current using the
AUXADC. The recommended resistor value is 10k.)
Protected by security key.
Battery Charger Thermal warning select
0 = Thermal Warning is ignored
1 = Thermal Warning pauses Battery Charger
Protected by security key.
Battery Charger OFF mask select
0 = OFF requests not masked
1 = OFF requests masked during Charging
Protected by security key.
