more pulse gen was interpolation and algorithms of multiple axes

The LPT would output a 12-byte burst on every interrupt.

Mariss,

Requesting confirmations / clarification(s).
So if we are "driving" a circular path, we would be sending changing/
changed pulse rates (likely SIN/COS derived) at the interrupt rate?
Which is currently set at 1024hz?

And the "rate" is in the form of a 2byte (16 bit) input? But the
available "speeds/rates" is 32768, so we don't use the full 16 bits ?

And the rates available are evenly spaced from 0 to the osc.(clock)
speed?

Where/ how do we change the direction? (direction bit driver input)
