Description
Analog Supply Voltage
AVDD is used to supply the on-chip PLL and the USB PAD.
Digital Ground
VSS is used to supply the buffer ring and the digital core.
USB Digital Ground
UVSS is used to supply the USB pads.
USB Pad Power Capacitor
UCAP must be connect to an external capacitor for USB pad power supply
(for typical application see
Digital Supply Voltage
VDD is used to supply the buffer ring on all versions of the device.
It is also used to power the on-chip voltage regulator of the Standard
versions or the digital core of the Low Power versions.
USB pull-up Controlled Output
VREF is used to control the USB D+ 1.5 kΩ pull up.
The Vref output is in high impedance when the bit DETACH is set in the
USBCON register.
