Electrical characteristics
• Fast pads - provide maximum speed. These are used for improved Nexus debugging capability.
• Input only pads - are associated with ADC channels and 32 kHz low power external crystal oscillator providing low
input leakage.
Medium and Fast pads can use slow configuration to reduce electromagnetic emission, at the cost of reducing AC performance.
