+Now whats important to note is that the DAC does not have an internal register so it doesn't load it into a register then "pull the trigger" to change the value for the output. As bits come streaming down DACY* they change the voltage. This means the voltage will jump around a little bit (therefore making the beam jump around). Luckily this happens rarely and is accounted for by BVLD... I think.
