In AB mode, the phase shift of the A and B input signals is used to determine
the pulse and direction. To do this, signals A and B are evaluated for rising
and falling edges.

b 2-way
c 4-way
The dots represent the points at which the count changes.
If the signal sequence is followed in the direction the arrow is pointing
(towards the right), this corresponds to a positive counting direction. If it is
followed against it, this corresponds to a negative counting direction.
