(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 VSS on the device itself and should not be connected to VSS on the circuit
board. If a crystal is not used and the clock input is driven directly, then the oscillator VSS may be connected to board ground.
(2) These I/O specifications do not apply to USB I/Os. USB0 I/Os adhere to USB2.0 specification.
(3) P = the period of the applied signal. Maintaining transition times as fast as possible is recommended to improve noise immunity on input
signals.
