5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors and configurable hysteresis.
I
5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors, configurable hysteresis, and analog input.
When configured as a ADC input, digital section of the pad is disabled, and the pin is not 5 V tolerant.
Tie together V
between both supplies is smaller than or equal to 0.5 V.
When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded
(grounding is preferred to reduce susceptibility to noise). XTALOUT should be left floating.

Description
PIO2_0 — General purpose digital input/output pin.
DTR — Data Terminal Ready output for UART.
Port 3 — Port 3 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 3 pins depends on the function
selected through the IOCONFIG register block. Pins PIO3_0, PIO3_1,
PIO3_3 and PIO3_6 to PIO3_11 are not available.
PIO3_2 — General purpose digital input/output pin.
PIO3_4 — General purpose digital input/output pin.
PIO3_5 — General purpose digital input/output pin.
3.3 V input/output supply voltage.
3.3 V supply voltage to the internal DC-DC converter and the ADC. Also
used as the ADC reference voltage.
Input to the oscillator circuit and internal clock generator circuits. Input
voltage must not exceed 1.8 V.
Output from the oscillator amplifier.
Thermal pad. Connect to ground.
