Description
Bit is set when external charge adapter has been

Bit is set when step down charger is operating
(independent of Reg. bit no_charging)
Bit is set when battery voltage has dropped below resume

Bit is set when charger is in trickle charge mode
Bit is set when charger is in top-off charge mode
(constant voltage mode)
Bit is set when charging has been terminated. Bit is
