L6482 tick period

Many of the equations for the motion controller within the L6482 use 250 ns as their time reference (tick). Does this value scale with clock frequency or is it divided by the appropriate values to always generate a 4MHz clock. I am trying to do high acceleration moves and the only way to do this seems to be getting tick down to a lower value. 125 ns ticks will get me what I need.

The tick time is internally generated by the system starting from the clock source (internal or external).

Reading carefully the datasheet I'm sure you can find the way to ''hack'' the system, however doing it could damage the IC. The tick is not the only internal timing the device must take care of.
