32 / 72 page  USB 2.0 Hi-Speed Hub Controller Datasheet Revision 1.0 (3-11-09) 32 SMSC USB251x DATASHEET behaviors provide battery charging even when the hub is not enumerated and protect the hub from sustained short circuit conditions. If the short circuit condition persists when the hub is plugged into a host system the user is notified that a port has an over-current condition. Otherwise the PRTPWR is turned on by the host system and the port operates normally. 7.3 Battery Charging Configuration Configuration of ports to support battery charging is done through a strap option on the corresponding ports PRTPWR[x] / BC_EN[x] pin. see Chapter 5, Pin Descriptions, or through EEPROM or SMBus configuration load. 7.3.1 Battery Charging enabled via EEPROM or SMBus Register memory map location 0xD0 is allocated for battery charging support. The "Battery Charging" register at location 0xD0 starting from Bit 1 enables battery charging for each downstream port when asserted. Bit 1 represents port 1 and so on. Each port with battery charging enabled asserts the corresponding PRTPWR[x:0] pin. |
