Electrical characteristics
• Slow pads — These are the most common pads, providing a good compromise between transition
time and low electromagnetic emission.
• Medium pads — These are provided in two types (M1 and M2) and provide transitions fast enough
for the serial communication channels. M2 pads include slew rate control.
• Fast pads — These provide maximum speed. There are used for improved NEXUS debugging
capability.
• SMD pads — These provide additional current capability to drive stepper motor loads.
• Digital I/O with analog (J) pad — These provide input and output digital features and analog input
for ADC.
M2 and Fast pads can disable slew rate to reduce electromagnetic emission, at the cost of reducing AC
performance.
