TPS65910A3 battery overcharging protection?

With regard to the TPS65910A3 it seems that this PMIC supports charging of Li-Ion batteries.  Is there any kind of overcharging protection built into the chip?

    Hello Mike,

    There is a backup battery charger, but this is not intended for LiIon, more like it's for a supercap.

    BBSEL Back up battery charge voltage selection: RW 0x0
    BBSEL[1:0] = 00 : 3.0 V
    BBSEL[1:0] = 01 : 2.52 V
    BBSEL[1:0] = 10 : 3.15 V
    BBSEL[1:0] = 11 : VBAT

    There are 4 settings, none of which represent a Li-Ion 4.2V charge profile.

    There is not a Li-Ion charger in this device.
