IN1 or IN2 works as an input block
(gate) for the other input.
IN1 is the counting input and IN2 is the
addition or subtraction directive input.
IN2 adds at L level and subtracts at H
level.
IN1 is addition input and IN2 is subtrac-
tion input.
Addition when the IN1 phase advances
beyond IN2, and subtraction when the
IN2 phase advances beyond IN1.

• Example where IN1 is the counting input and IN2 is the input block (gate).
• Example where IN2 is the counting input and IN1 is the input block (gate).
* “A” must be more than the minimum input signal width.
* “A” must be more than the minimum input signal width.
* IN1 and IN2 are completely independent, so there is no restriction on signal
* “B” must be more than the minimum input signal width.
