Hi,
It is possible to use single shunt resistor and connect the shunt resistor to reconstruct 3 phase current, but it is complex, especially when the state current is small or two PWM signal edge happens synchronously.
I attach DRM153.pdf, although the AN uses eFlexWM to generate PWM, but it also adapts to FTM which the K64 uses to generate PWM.
Hope it can help you
