OSC1 and OSC2 are connected to an RC network or a crystal (by mask op-
tion) for the internal system clock. In the case of RC operation, OSC2 is the
output terminal for 1/8 system clock. The system clock may come from the
crystal, the two pins cannot be floating.
Negative power supply, ground
Positive power supply
