DCOMP4 interrupt control
0 = interrupt when the source is less than
threshold
1 = interrupt when the source is greater
than threshold
(12-bit unsigned binary number)
CHG_ENA bit selects battery charger
current control
0 = Set battery charger current to zero
1 = Enable battery charge control
Protected by security key. Reset by state
machine. Default held in metal mask.
Selects what the end of charge current
should be set to
000 = 20mA
001 = 30mA
...
111 = 90mA
Protected by security key.

charge
0 = disable
1 = enable
Protected by security key. Reset by state
machine.
Time constant adjust for charger choke
recovery (step-up):
0 = Step-up time constant is 180us
(allows faster recovery between
processor wakeups)
1 = Step-up time constant is >20ms
(outside audio band)
(10mA steps)
