(1) When an external crystal is used oscillator (OSC_VSS) ground must be kept separate from other grounds and connected directly to the
crystal load capacitor ground. These pins are shorted to V_SS on the device itself and should not be connected to V_SS on the circuit
board. If a crystal is not used and the clock input is driven directly, then the oscillator V_SS may be connected to board ground.
(2) Whichever is smaller. P = the period of the applied signal. Maintaining transition times as fast as possible is recommended to improve
noise immunity on input signals.
