Charger Status.
0 = Battery Charging is inactive
1 = Battery Charging is active
(Note CHG_ENA is just a request; the WM8352
determines if the conditions are satisfied for
Battery Charging).
Default held in metal mask.
0 = Don't pause the charger
1 = Pause charging
Reset by state machine.
00 = Charger off, current set to 0.
01 = In trickle charge mode.
10 = In fast charge mode.
11 = Reserved
Writing to his field set the charge timeout
duration:
0000 = 60min
0001 = 90min
0010 = 120min
0011 = 150min
0100 = 180min
0101 = 210min
0110 = 240min
0111 = 270min
1000 = 300min
1001 = 330min
1010 = 360min
1011 = 390min
1100 = 420min
1101 = 450min
1110 = 480min
1111 = 510min
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.
Battery charge voltage:
00 = 4.05V
01 = 4.1V
10 = 4.15V
11 = 4.2V
Protected by security key.
Fast charge current limit setting.
