HS USB PCI Host Controller
[1]
Symbol names ending with a ‘#’ (for example, NAME#) represent active LOW signals for PCI pins. Symbol
names with an overscore (for example, NAME) represent active LOW signals for USB pins.
[2]
The pull-up resistor must always be present even if I2C EEPROM is not used.
[3]
If legacy support is not used, connect this pin to ground.
