(1) When an external crystal is used, oscillator (OSC_VSS, RTC_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) Unless specifically indicated, these I/O specifications do not apply to USB I/Os. USB0 I/Os adhere to USB2.0 specification. USB1 I/Os
adhere to USB1.1 specification.
(3) 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.
