Primary Uni-3 Interface; Primary Uni-3 Connector Description - Motorola 56F805 Hardware User Manual

2.11 Primary UNI-3 Interface

Motor control signals from a family of motor driver boards can be connected to the EVM
board via the Primary UNI-3 connector/interface. The Primary 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 controller's input and output ports: A/D,
TIMER and PWM A. Refer to
