Crystal connection 1 (48 or 12MHz depending on TEST1 pin)
Crystal connection 2 (48 or 12MHz depending on TEST1 pin)
Programmable output clock for external devices
Voltage supply 3.3V
Over-current notice to the device. This pin is also used to sense the USB VBUS.
A LOW on this pin of less than 2 seconds is interpreted as an overcurrent notice;
longer than 2 seconds is interpreted as loss of VBUS.
Enables power to downstream ports
Device is in suspended state
