Product data sheet
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).
5 V tolerant pad with 5 ns glitch filter providing digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad with 20 ns glitch filter providing digital I/O function with TTL levels and hysteresis.
Pad provides special analog functionality.
When the main oscillator is not used, connect XTAL1 and XTAL2 as follows: XTAL1 can be left floating or can be grounded (grounding
is preferred to reduce susceptibility to noise). XTAL2 should be left floating.
