the value of the DIR signal. A low at DIR triggers a
countup; a high causes the setup to count down. Fig-
ure 17 shows a countup sequence followed by a count-
down sequence, both across the zero position.

DIR
DIR-INC mode
In DIR-INC mode a change in angle for both directions
of rotation generates an output pulse for signal CLK ^NCLR
(pin A). Signal DIR (pin B) gives the direction of ro-
tation. This mode permits the operation of external
binary counter modules (such as 74HC/HCT191, for
example), with signal NCLR (pin C) being used to re-
set the external counter. With a rising edge at CLK the
counter status is counted up or down, depending on

As a general rule our developments, IPs, principle circuitry and range of Integrated Circuits are suitable and specifically designed for appropriate use in technical
applications, such as in devices, systems and any kind of technical equipment, in so far as they do not infringe existing patent rights. In principle the range of
use is limitless in a technical sense and refers to the products listed in the inventory of goods compiled for the 2008 and following export trade statistics issued
annually by the Bureau of Statistics in Wiesbaden, for example, or to any product in the product catalogue published for the 2007 and following exhibitions in
Hanover (Hannover-Messe).
We understand suitable application of our published designs to be state-of-the-art technology which can no longer be classed as inventive under the stipulations
of patent law. Our explicit application notes are to be treated only as mere examples of the many possible and extremely advantageous uses our products can
be put to.
