Help with "special" motor driver (aka A2918)

Hi there!

This is my first post so I feel kinda nervous. Anyway this is my problem: I salvaged some old printer and I came across a discontinued motor driver which has some pins I don't have the slightest idea how to use.

I'm familiar with the L298 so I understand the basics. What is new to me are the pins 5 (LOAD SPLY), 15 (REFERENCE), and the cluster of pins for the pwm: RC, PHASE and -ENABLE.

I couldn't get it running specially because I can't figure out how to set the inputs. I'll really apreciate if someone could help me understand how to use this driver.

Here's the datasheet I took the image from:
