This section explains the basic usage of the QD62(E/D).
Six types of the pulse input methods are available. These include 1 phase multiple of 1,
1 phase multiple of 2, CW/CCW pulse input, 2 phase multiple of 1, 2 phase multiple of
2, and 2 phase multiple of 4. The following table shows the pulse input methods and
count timings.
