DESCRIPTION
Connect to Ground for 48MHz crystal input.
Connect to VCC for 12MHz crystal input.
Connect to Ground
Connect to Ground
Power-on reset
Ground reference
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 ± 0.3V
Overcurrent 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
