2.11 UNI-3 Interface
Motor control signals from a family of motor driver boards can be connected to the EVM board
via the UNI-3 connector/interface. The UNI-3 connector/interface contains all of the signals
needed to drive and control the motor drive boards. These signals are connected to differing
groups of the device’s input and output ports: A/D, TIMER and PWM. Refer to
pin out of the UNI-3 connector.
