I = input, O = output, AI/O analog input/output, IA = inactive; PU = pull-up enabled (weak pull-up resistor pulls up pin to V
DD(IO)
); F =
floating. Reset state reflects the pin state at reset without boot code operation.

5 V tolerant pad with 15 ns glitch filter (5 V tolerant if V
DD(IO)
present; if V
DD(IO)
not present, do not exceed 3.3 V); provides digital I/O
functions with TTL levels and hysteresis; normal drive strength.

5 V tolerant pad with 15 ns glitch filter (5 V tolerant if V
DD(IO)
present; if V
DD(IO)
not present, do not exceed 3.3 V) providing digital I/O
functions with TTL levels, and hysteresis; high drive strength.
