7.3. Setting of the division rate of the index divider
These settings use the same rules and codes as shown with the main divider (see section 6)

7.4. Position and width of the index pulse
For illustration of the functions, the drawings of this chapter assume that the main impulse
divider of the A/B input pulses would be set to 8. The index pulse will appear at the output
according to the division rate set (see section 7.3 above).
DIL2
Small index pulse (1/4 of the input period time)
