Input/Output Function
Input and output USB2.0 Host/Function Module bus D+ data.
Input and output USB2.0 Host/Function Module bus D- data.
Input USB cable connection monitor pin. Connect to the USB bus
VBUS. VBUS connection/disconnection can be detected. If not
connected to the USB bus VBUS, fix to 5 V. Supply 5 V during
host controller function selection as well.
Input This pin is for connection to the reference resistor.
Connect to USBAPVss via 5.6 kΩ ± 1% resistor. (QFP)
Connect to Vss via 5.6 kΩ ± 1% resistor. (BGA package)
Input Connects the USB crystal oscillator. USB_X1 pin can also input
the external clock.
