L6207 PWM Current Control Question

Could someone please explain how current is controlled on the L6207 via onboard PWM Current Controller?  Additionally, AN1762 APPLICATION NOTE indicated a constant current could be obtained through a simple voltage divider into Vref.  
For example, I want to cap the current at 1.5A / phase, what type of PWM or voltage division would I need to implement? 
Thank you.
