Bit Field Name Access Description
7:4 RSVD RO Reserved. Read only, returns 0 when read.
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, i.e. batEn0 corresponds to
downstream port 0. When in I
2
C/SMBus mode the bits in this field
corresponding to the enabled ports per used[3:0] may be over-written by
3:0 batEn[3:0] RW
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.

Removable. The bits in this field indicate whether a device attached to
downstream ports 3 through 0 are removable or permanently attached. A
value of 0 indicates the device attached to the port is not removable. A
value of 1 indicates the device attached to the port is removable.
3:0 rmbl[3:0] RW The default value for these bits are loaded at the de-assertion of reset
with the value of LEDA[3:0]z_RMBL[3:0] as follows:
rmbl[3:0] defaults to wxyzb,
where w is LEDA3z_RMBL3, x is LEDA2z_RMBL2, y is LEDA1z_RMBL1
and z is LEDA0z_RMBL0.
