7:4 | RSVD | RO | Reserved. Read only, returns 0 when read. |
3:0 | batEn[3:0] | RW | Battery Charger Support.
The bits in this field indicate whether the downstream port
implements the charging port features. A value of 0 indicates the
port does not implement the charging port features. A value of 1
indicates the port does support the charging port features. Each bit
corresponds directly to a downstream port, for example. batEn0
corresponds to downstream port 0. When in I2C/SMBus mode
the bits in this field corresponding to the enabled ports per
used[3:0] may be over-written by EEPROM contents or by an SMBus
host. |

The default value for these bits are loaded at the de-assertion of reset with the value of the PWRON[3:0]z_BATEN[3:0] as follows: |
| bateEn[3:0] defaults to wxyzb, |
where w is PWRON3z_BATEN3, x is PWRON2z_BATEN2, y is PWRON1z_BATEN1 and z is PWRON0z_BATEN0. |
