Current Sink 1 enable (ISINKA pin)
0 = disabled
1 = enabled
Reset by state machine.
Current Sink 1 behaviour in Hibernate mode
0 = disable current sink in Hibernate
1 = leave current sink as in Active
Reset by state machine.

… (50mA steps)
1111 = 750mA
Note: Do not set the charger to be more than
400mA when USB powered.
Protected by security key.
Allows trickle-charging to be forced even if the
battery voltage is above the default threshold
0 = only trickle-charge if the battery voltage is
below CHG_VSEL-100mV
1 = always trickle-charge
Protected by security key. Reset by state
machine.
Time between steps when the charger throttles
back due to USB current limit.
00 = 8us
01 = 16us
10 = 32us
11 = 128us
