Horizontal output pulse phase
HPHCEN
Measure the delay between the rise of the pin
23 horizontal output pulse and the fall of the Y
IN horizontal synchronizing signal when
HPHASE is set to 0 and when it is set to 7,
and calculate the difference between those
measurements and HPH

HPHrange
Measure the delay between the rise of the pin
23 horizontal output pulse and the fall of the
SYNC IN horizontal synchronizing signal as
HPHASE is set to each value from 0 to 7, and
calculate the amount of the change at each step.
Find the step size with the largest change.

Connect a DC voltage source to pin 25 and
gradually increase the voltage starting at 0 V.
Measure the pin 25 DC voltage at the point that
the pin 23 horizontal pulse output stops.
