Reading from this field indicates the charge

time remaining:

Time remaining = CHG_TIME * 2048s

Protected by security key. Default held in metal

mask.

CHG_MASK_WALL_FB

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.

CHG_TRICKLE_SEL

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.

5:4

CHG_VSEL[1:0]

Battery charge voltage:

00 = 4.05V

01 = 4.1V

10 = 4.15V

11 = 4.2V

Protected by security key.

3:0

CHG_ISEL[3:0]

0110

Fast charge current limit setting.

0000 = off

0001 = 50mA

0010 = 100mA

… (50mA steps)

1111 = 750mA

Note: Do not set the charger to be more than

400mA when USB powered.

Protected by security key.
