All VSS pins must be connected together in the application. Because fast signal
transitions place high, short-duration current demands on the power supply, use
bypass capacitors with high-frequency characteristics and place them as close to
the MCU as possible. Bypass requirements depend on MCU pin load.

For More Information On This Product,
Internal power and ground generated by internal regulator. These also
allow an external source to supply the core VDD/VSS voltages and
bypass the internal voltage regulator.
External power and ground, supply to internal voltage regulator.
To disable voltage regulator attach V
External power and ground, supply to pin drivers.
Operating voltage and ground for the analog-to-digital converter, the
reference for the internal voltage regulator and the digital-to-analog
converters, allows the supply voltage to the A/D to be bypassed
independently.
Reference voltage high for the ATD converter, and DAC.
Reference voltage low for the ATD converter.
Provides operating voltage and ground for the Phased-Locked Loop.
This allows the supply voltage to the PLL to be bypassed
independently. Internal power and ground generated by internal
regulator.
