27 This entry shows and sets the maximum time the max14577
28 charger operates in fast-charge mode. When the timer expires
29 the device will terminate fast-charge mode (charging current
30 will drop to 0 A) and will trigger interrupt.

55 This entry shows and sets the charging current threshold for
56 entering top-off charging mode. When charging current in fast
57 charge mode drops below this value, the charger will trigger
58 interrupt and start top-off charging mode.
