The Z/CLR clears the value of the up/down counter. This pin is
usually connected with the index signal of a rotary encoder or a
linear scale.
The B/DN is the count pulse input B or DN.
The A/UP is the count pulse input A or UP.
The condition of these three pins(SEL 0, SEL 1 and SEL 2)
specifies the counter operation mode. See the Table 4.
The DIR selects the count direction of the up/down counter.
The UD/AB selects the input pulse mode(up/down or not).
