Phase Z output is 80 times in motor 1-rotation based on rise up or rise down edge of Phase
A or Phase B with the width of one pulse of Phase A. (does not determine the position
relation of Phase Z or Phases A&B.
✔
When other than 1/1 is set as division ratio, Phase A and Phase B are divided but Phase Z is
output with original pulse width.
