Bidirectional differential data pin (D- per USB
specification).
Bidirectional differential data pin (D+ per USB
specification).
Used in Host mode to control an external
power source to supply power to the USB bus.
Used in Host mode by an external power
source to indicate an error state by that power
source.
9.1 KOhm resistor (1% precision) used
internally for USB analog circuitry.
Power source for the Hibernation Module. It
is normally connected to the positive terminal
of a battery and serves as the battery
backup/Hibernation Module power-source
supply.
