At low speeds yes. The output waveform shows clearly its in the discontinous mode but above around 10% the compressor is so noisy you cant tell anyway and it starts to enter the continuos mode. After its recieved 50 pulses within +/- 32uS it takes this as the zero position and theres a little subroutine that then sweeps from 200Hz to 1kHz and back with a 3% duty cycle to create an audiable tone to let me know its received this signal and is ready to turn on. To my suprise this actually moves the motor slightly but as its a compressor it doest matter.

If you would like a copy of the source code/circuit I can Email it to you.
