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 various groups of the DSP's input and output ports; A/D, TIMER
and PWM Port A. The header, JG14, is used to select between the Back-EMF and Motor
Phase Current signals. Refer to
J1.
