Description
Alternate Ground
AVSS is used to supply the on-chip PLL and the USB PAD.
Alternate 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.
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.
