Possibility to change the phase shift offset with the ST L6230

Hi,

I have a control board with the MCU F302R8, and a power board with the ST L6230. For my tests, I want to shift the motor phase voltages, so that the phase shift offset is not 120 degrees, and I want to be able to change the offset manually. My question is: is this actually possible with the ST L6230? Or shall I look for another motor driver?
