x = available; - = not pinned out.
I = input, O = output, IA = inactive; PU = pull-up enabled (weak pull-up resistor pulls up pin to V
the pin state at reset without boot code operation.
5 V tolerant pad with 15 ns glitch filter; provides digital I/O functions with TTL levels and hysteresis; normal drive strength.
5 V tolerant pad with 15 ns glitch filter providing digital I/O functions with TTL levels, and hysteresis; high drive strength.
5 V tolerant pad with 15 ns glitch filter providing high-speed digital I/O functions with TTL levels and hysteresis.
5 V tolerant pad providing digital I/O functions (with TTL levels and hysteresis) and analog input or output. When configured as a ADC
input or DAC output, the pin is not 5 V tolerant. For analog functionality, disable the digital section of the pad by setting the pin to an
input function and by disabling the pull-up resistor through the corresponding SFSP register.
5 V tolerant transparent analog pad.
For maximum load C
VBUS = 0.2 V when it is no longer driven.
