It is mandatory to connect all available VDD and VAREF pins to the supply voltage and all VSS and VSSA pins to ground.

OSC1 and OSC2 pins connect a crystal/ceramic resonator, or an external source to the on-chip oscillator; see Section 1:

Description and Section 19.5: Clock and timing characteristicsfor more details.
