STEPPER PHASE CORRECTION
1A
TR to Stepper Phase Correction - MSB
n n n n n n
First step of scan occurs n pixels (1 - 16383) after first
TR pulse. This register can be used to set the phase
between the TR pulses and the stepper motor pulses.
NOTE: a setting of n = 0 creates the maximum delay
(16384) pixels, which will increase scan time. If this
function is not used, this register should be set to 1.
