Reading from this field indicates the charge
time remaining:
Time remaining = CHG_TIME * 2048s
Protected by security key. Default held in metal
mask.
Selects whether to ignore the WALL_FB signal
when charging from LINE.
0 = Does not mask the WALL_FB signal
1 = Mask the WALL_FB signal.
Note: Care needs to be taken when using this
bit.
Protected by security key. Reset by state
machine.
Selects the trickle charge current.
0 = Set the trickle charge current to 50mA.
1 = Set the trickle charge current to 100mA.
Protected by security key.
