[10] Pad provides special analog functionality. A 32 kHz crystal oscillator must be used with the RTC.
[11] When the system oscillator is not used, connect XTAL1 and XTAL2 as follows: XTAL1 can be left floating or can be grounded (grounding

Product data sheet
Open-drain 5 V tolerant digital I/O pad, compatible with I
output functionality. When power is switched off, this pin connected to the I
Open-drain configuration applies to all functions on this pin.
Pad provides digital I/O and USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and
Low-speed mode only). This pad is not 5 V tolerant.
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad with TTL levels and hysteresis. Internal pull-up and pull-down resistors disabled.
5 V tolerant pad with TTL levels and hysteresis and internal pull-up resistor.
5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
