    {
      accumulator ++;
    }
else
    {
     accumulator --;
    }

I chose 127 just for simplicity.

Just as easily, you could test for the actual value.

if (pwm03 == 255)
    {
      accumulator ++;
    }
else
    {
     accumulator --;
    }

I was attempting to understand what the PHASE B was, i now know, and was just expressing how i was going to do it with out it in my specialized case. That code you wrote is exactly what i had described, and what has been in our code for a while now.
