Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7:2 | RSVD | R | 0Xh | Reserved. Read only, returns 0 when read. |
1:0 | batEn[1:0] | R/W | 0Xh | Battery Charger Support. The bits in this field indicate whether the downstream port implements the charging port features. 0 = The port is not enabled for battery charging support features 1 = The port is enabled for battery charging support features Each bit corresponds directly to a downstream port, that is batEn0 corresponds to downstream port 1, and batEN1 corresponds to downstream port 2. The default value for these bits are loaded at the deassertion of reset with the value of PWRCTL/BATEN[1:0]. When in I2C/SMBus mode the bits in this field can be overwritten by EEPROM contents or by an SMBus host. |
