This pin should be connected to the D- pin of the USB
bus.
VBUS input
Input USB cable connection monitor pin
This pin should be connected directly to the VBUS of
the USB bus. Whether the VBUS is connected or
disconnected can be detected.
If this pin is not connected with the VBUS of the USB
bus, it should be supplied with 5 V. It should be
supplied with 5 V also when the host controller function
is selected.
Reference input Input Reference resistor connection pin
This pin should be connected to AG33 through a
5.6 kΩ ±1% resistor.
Crystal input
output pin
(Clock input pin)
Input
These pins should be connected to crystal oscillators
for the USB. The EXTAL_USB pin can be used for
external clock input.
Output These pins should be connected to crystal oscillators
for the USB.
