Battery Charging Configuration
The battery charging option can be configured in one of two ways:
When the hub is brought up in the default configuration with strapping options enabled, with the
PRTPWR1/BC_EN1 pin configured (Port 1 only). See the following sections for details:
Section 2.3: Pin Descriptions (Grouped by Function) on page 11
Section 2.5: Strap Pin Configuration on page 14
When the hub is initialized for configuration over SMBus.
3.2.1
Battery Charging Enabled via 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 bit 2 represents port 2. Each port that has battery charging
enabled asserts the corresponding PRTPWR[2:1] pin.
