Note: I/T: Input type; O/T: Output type
OP: Optional by configuration option (CO) or register option
PWR: Power; CO: Configuration option; ST: Schmitt Trigger input
CMOS: CMOS output;
NMOS: NMOS output
AN: Analog input pin
VDD is the device power supply while AVDD is the ADC power supply.
VSS is the device ground pin while AVSS is the ADC ground pin.
As the Pin Description Summary table applies to the package type with the most pins, not all of the
above listed pins may be present on package types with smaller numbers of pins.
