The CE bit state is latched inside the charger control logic (CE latch) during an OUT pin UVLO event, prior to resetting the charge
control register bit CE to its power up default value. The charger CE latch controls the charger and power path state as long as the
TPS65800 is in UVLO mode and an external supply is connected to the charger block. The CE latch is reset to its power-up value
(CE=HI) only when the input power is removed from the charger block. The CE latch is disabled and the CE charge control register bit
sets the charger and power path MOSFETs state when the TPS65800 exits the UVLO mode. This feature avoids a host software loop
when the host algorithm requires a depleted (or absent) battery to be connected to the system bus while input power is present.

The battery supplement is entered when V(BAT)– V(OUT) > 60 mV (typ), and it ends when V(BAT)– V(OUT) < 20 mV. When the system
power bus current exceeds the input current limit or the external supply current capability, the supplement mode is set. An oscillatory
behavior for BAT_STAT bit can happen if the battery switch dropout voltage is less than 20 mV (typ) when in supplement mode.
(2)
The BAT_STAT is always masked internally, and does not generate interrupts.
(3)
The ACPG and USBPG bits have valid data only when V(LDO_PM) > 2.0 V.
