4.6.1
The device provides four main I/O pad types depending on the associated alternate functions:
Also, medium/slow and fast/medium pads are available in design which can be configured to behave like a slow/medium and
medium/fast pads depending upon the slew-rate control.
Medium and fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.

Where:
Slow pads—These pads are the most common pads, providing a good compromise between transition time and low
electromagnetic emission.
Medium pads—These pads provide transition fast enough for the serial communication channels with controlled
current to reduce electromagnetic emission.
Fast pads—These pads provide maximum speed. These are used for improved Nexus debugging capability.
Input only pads—These pads are associated to ADC channels and 32 kHz low power external crystal oscillator
providing low input leakage.
Low power pads—These pads are active in standby mode for wakeup source.
